About the post: Amidst the proliferation of material technologies developed to solve the problems of planetary climate change and carbon emissions, the technoscientific community increasingly champions a new molecular hero: metal organic frameworks (MOFs). Metal organic frameworks are an emergent generation of material technologies lauded for their capacity to capture and sequester carbon dioxide (CO2) within their porous structures. They are among the most widely researched materials within the fields of climate science, materials science, and various (sub)disciplines of chemistry, heralded for potential applications that include yet exceed carbon capture and sequestration. Their synthesis anticipates infinite configurations of matter and materiality at the molecular scale, with an equally infinite array of applications. This article examines the promise and porosity of MOFs created to capture CO2.

La historia de la humanidad ha estado marcada por los materiales que hemos sido capaces de crear y dominar. Desde la piedra y el bronce hasta el silicio y los superconductores, la Química ha sido la llave que nos ha permitido construir civilizaciones, desafiar las leyes de la naturaleza y expandir nuestras fronteras. En el programa de esta semana analizamos algunos de los materiales que están llamados a revolucionar el mundo los próximos años, desde el popular grafeno hasta los menos conocidos MOFs o a la fascinante tecnología Magnónica, Todo ello de la mano de Dani Torregrosa, Ginesa Blanco y Ávaro Martínez.

What is the future of dehumidification? Turns out this simple question opens up an exciting view of the future of IAQ generally. The goal of a low energy method for removing water molecules from a flowing airstream boils down to some way of identifying, grabbing and holding onto them. Essentially we are talking about a designer desiccant or molecular filter that lets the air pass through while it filters out water molecules. If we can do this, the next logical question is “Why stop there?” Why not identify a broad range of pollutants and contaminants in the airstream and also select and remove them as well? Enter metal molecularly sensitive filtration based on Metal Oxide Framework (MOF) technology. MOFs are a type of advanced material that scientists are developing to tackle a wide range of challenges, from clean energy, to environmental protection via direct air carbon capture (DACC), to health and drug delivery.. While the name may sound complex, the basic idea behind MOFs is relatively simple—they are materials made by combining metal ions (like zinc, iron, or copper) with organic molecules to create a kind of 3D structure that is highly porous, meaning it has lots of tiny holes or cavities - and they operate as a molecular sieve or filter. Join Kristof as he interviews Todd DeMonte of Madison IAQ to unpack the future of dehumidification and learn about desiccants, and the potential for metal oxide frameworks. Along the way we learn whether the “good old” compressor-based dehumidifier is likely to remain the preferred and appropriate approach for many years to come. This is an episode that will bring you up to date at this important edge of the industry.

Welcome back! Join Dylan and Julian Turecek, CEO of AspiraDAC, in this episode of Hardware to Save a Planet and explore the exciting world of direct air capture (DAC) technology and its potential for CO2 removal from the atmosphere. Julian shares his insights on the energy requirements, challenges, and cost-effectiveness of DAC. Discover AspiraDac's innovative approach of integrating renewable energy supply with capture technology and how they use metal-organic frameworks (MOFs) as carbon absorbent materials.

If hydrogen is to be used as a fuel, it will need to be stored. MOFs or metal organic frameworks are highly absorbent compounds which absorb and easily release hydrogen.

Matter is that which takes up space, and has mass. It is what we interact with, and what we are. Imagining a world without matter is to imagine light particles drifting aimlessly in space. Gasses, liquids, solids, and plasmas are all states of matter. Material science studies all of these, and their combinations and intricacies, found in examining foams, gels, meshes, and other materials and metamaterials. Chris Cogswell is a material scientist, and host of The Mad Scientist Podcast, a podcast that takes a critical look at things ranging from technological fads, to pseudoscience, and topics that deserve a critical eye. On the first of a pair of two episodes about material science, we interview Chris about his experience with studying material science, and ask questions about the subject in general.

Considering that finite resources such as precious metals are among these wastes, the opportunity appears obvious. Wendy Lee Queen, and American expat and passionate baseball player, leads the Laboratory for Functional Inorganic Materials at the EPFL in Lausanne, and has a potential solution. She is one of the leading experts of metal organic frameworks (MOF) and a pioneer of novel composite materials where MOFs and polymers in bead form provide an innovative way to fine tune affinity and selectivity for various chemical species of interest. These can be used to efficiently capture pollutants such as carbon dioxide, but also to recover valuable resources from water waste streams, such as precious metals.Wendy's research is a beautiful story of chemical innovation, where ground-breaking chemistry makes new things possible. And when these new things have the potential to change the way we look at our urban and industrial wastes, this is a moment chemistry is brought to life.

The International Panel on Climate Change (IPCC) released a report this month outlining how bad climate change is, how bad it will be, and what will happen if we don't make drastic changes in the way we address the crisis. But that doesn't mean we will not be able to come up with clever solutions to help prevent some of the most extreme and dire consequences of climate change. Let's talk about the what the IPCC report states and one potential solution we could utilize, metal organic frameworks (MOFs) and carbon capture.

Jeff Klunzinger, co-founder of OS Fund (osfund.co), delivers an overview of investing for change, and how his company is putting money to work in all the right places, affecting change and improving lives. OS Fund's objective is to invest in skilled entrepreneurs who are making commercially viable advances in artificial intelligence, genomics, synthetic biology, automation, new materials development, and more, to solve real-world problems. From using bacteria to capture carbon and clean the air, to applying technology to augment crop growth in hunger-stricken areas, OS Fund seeks to make a positive imprint on the world by funding those who can make a difference. In just four quick years the fund has invested in 28 companies that are doing the work to make that difference in the world. The investment executive provides some interesting details on some of the enterprises his company funds. NuMat Technologies, for example, is a leader in the design of MOFs (Metal-Organic Frameworks), which are atomically-engineered materials with immense surface areas, extremely tunable porosities, and practically limitless combinatorial possibilities. NuMat's MOFs can make a major impact on the planet as they can filter water from the air, xenon from the ocean, and even increase storage for gas by scientifically increasing surface area. Another innovative company OS Fund has capitalized is Ginko Bioworks, an organism company. Ginko Bioworks designs tailored microbes for multiple customers in numerous markets. By utilizing software and hardware automation, Ginko Bioworks' synthetic biology engineers are able to produce new organisms that replace tech with biology.  While many technologies require excessive capital expenditure to bring their advances to the marketplace, OS Fund looks for ‘ready-to-go' technologies that can be rolled out for a doable expenditure and thus bring them to market sooner. By taking minimal scientific risks and focusing heavily on the technological side of projects, Klunzinger's OS Fund is able to capitalize more companies making a difference.  Klunzinger expounds upon the next stage synthetic biology applications that will be coming soon, such as the use of computational tools that can, remarkably, produce brand new proteins. Additionally, he talks about exciting new companies that focus on the microbiome, which are the microorganisms in a distinct environment (including the body or a specific part of the body). And as individuals utilize microbiome testing they can begin to study and make an impact on their health. And the funding strategist also discusses how AI is now rolling into nearly all the companies they assist monetarily.  Ultimately, OS Fund seeks to capitalize companies that impact the entire world positively with advanced technological innovations, big vision companies with a pragmatic sensibility. While Klunzinger likes careful craftsmanship of ideas, his fund looks for signs that the company understands the value of the equity they are seeking, so once capitalization occurs, the company is ready to roll straight forward toward commercialization.

The aim of this work is to further the understanding of the important parameters in the formation process of 2D nanostructures and therewith pioneer for novel applications. Such 2D nanostructures can be composed of specially designed organic molecules, which are adsorbed on various surfaces. In order to study true 2D structures, monolayers were deposited. Their properties have been investigated by scanning tunneling microscopy (STM) under ultra-high vacuum (UHV) conditions as well as under ambient conditions. The latter is a highly dynamic environment, where several parameters come into play. Complementary surface analysis techniques such as low-energy electron diffraction (LEED), X-Ray photo-emission spectroscopy (XPS), and Raman spectroscopy were used when necessary to characterize these novel molecular networks. In order to conduct this type of experiments, high technical requirements have to be fulfilled, in particular for UHV experiments. Thus, the focus is on a drift-stable STM, which lays the foundation for high resolution STM topographs. Under ambient conditions, the liquid-solid STM can be easily upgraded by an injection add-on due to the highly flexible design. This special extension allows for adding extra solvent without impairing the high resolution of the STM data. Besides the device, also the quality of the tip is of pivotal importance. In order to meet the high requirements for STM tips, an in vacuo ion-sputtering and electron-beam annealing device was realized for the post-preparation of scanning probes within one device. This two-step cleaning process consists of an ion-sputtering step and subsequent thermal annealing of the probe. One study using this STM setup concerned the incorporation dynamics of coronene (COR) guest molecules into pre-existent pores of a rigid 2D supramolecular host networks of trimesic acid (TMA) as well as the larger analogous benzenetribenzoic acid (BTB) at the liquid-solid interface. By means of the injection add-on the additional solution containing the guest molecules was applied to the surface. At the same time the incorporation process was monitored by the STM. The incorporation dynamics into geometrically perfectly matched pores of trimesic acid as well as into the substantially larger pores of benzentribenzoic acid exhibit a clearly different behavior. For the BTB network instantaneous incorporation within the temporal resolution of the experiment was observed; for the TMA network, however, intermediate adsorption states of COR could be visualized before the final adsorption state was reached. A further issue addressed in this work is the generation of metal-organic frameworks (MOFs) under ultra-high vacuum conditions. A suitable building block therefore is an aromatic trithiol, i.e. 1,3,5-tris(4-mercaptophenyl)benzene (TMB). To understand the specific role of the substrate, the surface-mediated reaction has been studied on Cu(111) as well as on Ag(111). Room temperature deposition on both substrates results in densely packed trigonal structures. Yet, heating the Cu(111) with the TMB molecules to moderate temperature (150 °C) yields two different porous metal coordinated networks, depending on the initial surface coverage. For Ag(111) the first structural change occurs after annealing the sample at 300 °C. Here, several disordered structures with partially covalent disulfur bridges were identified. Proceeding further in the scope of increasing interaction strength between the building blocks, covalent organic frameworks (COFs) were studied under ultra-high vacuum conditions as well as under ambient conditions. For this purpose, a promising strategy is covalent coupling through radical addition reactions of appropriate monomers, i.e. halogenated aromatic molecules such as 1,3,5-tris(4-bromophenyl)benzene (TBPB) and 1,3,5-tris(4- iodophenyl)benzene (TIPB). Besides the correct choice of a catalytic surface, the activation energy for the scission of the carbon-halogen bonds is an essential parameter. In the case of ultra-high vacuum experiments, the influence of substrate temperature, material, and crystallographic orientation on the coupling reaction was studied. For reactive Cu(111) and Ag(110) surfaces room temperature deposition of TBPB already leads to a homolysis of the C-Br bond and subsequent formation of proto-polymers. Applying additional heat facilitates the transformation of proto-polymers into 2D covalent networks. In contrast, for Ag(111) just a variety of self-assembled and rather poorly ordered structures composed of intact molecules has emerged. The deposition onto substrates held at 80 K has never resulted in proto-polymers. For ambient conditions, the polymerization reaction of 1,3,5-tri(4-iodophenyl)benzene (TIPB) on Au(111) was studied by STM after drop-casting the monomer onto the substrate held either at room temperature or at 100 °C. For room temperature deposition only poorly ordered non-covalent arrangements were observed. In accordance with the established UHV protocol for halogenated coupling reaction, a covalent aryl-aryl coupling was accomplished for high temperature deposition. Interestingly, these covalent aggregates were not directly adsorbed on the Au(111) surface, but attached on top of a chemisorbed monolayer comprised of iodine and partially dehalogenated TIPB molecules. For a detailed analysis of the processes, the temperature dependent dehalogenation reaction was monitored by X-ray photoelectron spectroscopy under ultra-high vacuum conditions.

Phosphonic acids and lanthanides are both promising building blocks for the synthesis of new metal organic frameworks (MOFs). However, their chemical and structural flexibility challenges the tailoring of well defined crystalline structures. This work is focused on overcoming this lack of control with the introduction of 1,4-phenylenbis(methylidyne)-tetrakis(phosphonic acid), H8L, a molecule that combines a rigid spacer and two ligands suitable for the chelation of large ions. Using a synthetic high-throughput approach, H8L was investigated as new molecular building block for the formation of coordination frameworks with lanthanides (Ln = La, Nd, Gd, Dy) under hydrothermal conditions. Thereby, 14 new lanthanide phosphonates were discovered, categorized into three structure types and their crystallization fields described. Structure type I comprises six compounds with the general formula Ln(H5L). The examples of Ln[(PO3H)2CH-C6H4-CH(PO3H)(PO3H2)]∙4H2O, where Ln = La, Nd, reveal two-dimensional coordination networks having a layered structure, but differ in the layer stacking. Structure type II comprises 4 compounds of the general formula Ln2(H2L) and is represented by La2[(HO3P)(O3P)-CH-C6H4-CH-(PO3)(PO3H)] ∙8H2O, a layered structure with dimeric lanthanum coordination polyhedra. Four compounds of the type NaLn(H4L) are in stucture type III, which was solved from NaLa[(PO3H)2CH-C6H4-CH(PO3H)2]∙4H2O. This structure consists of a three-dimensional open framework with La3+ coordinated by bisphosphonate units in an exclusively bidentate fashion. It provides one-dimensional rhombic channels which are occupied by sodium ions and water molecules acting as guests. The anionic, open-framework of the new MOF NaLa(H4L) exhibits an exceptional selectivity for monovalent metal cations. The presented work elucidates the relationship between the ion-exchange behavior and the framework flexibility: The exchange of the Na+ ions in NaLa(H4L) with alkaline-earth, alkaline and selected transition metal ions was studied. EDX and ICP-OES elemental analysis revealed that ion exchange was successful with monovalent ions, while higher-valent ions were rejected. An explanation for this charge selectivity could be found in the site-specific role of the guest cation. X-ray diffraction and thermogravimetric studies on the reversible hydration and dehydration behavior demonstrate that NaLa(H4L) has a flexible framework. Contraction of the channels upon dehydration leads to a decrease in the cell volume by 15%. Rietveld refinement of the structure of the dehydrated form NaLa(H4L)dehyd revealed the key role played by the guest cation in the channel-shrinking mechanism. In the hydrated, expanded form, each Na+ ion guest shares three phosphonate oxygens with a La3+ ion in a lanthanum phosphonate chain that defines part of the wall of a rhombic channel. The Na+ ion completes its octahedral coordination sphere with two water molecules and a weaker bond to a fourth phosphonate oxygen. In the dehydrated, contracted form, the Na+ ion loses the two water molecules and moves towards a second La3+ ion, which is located in an adjacent lanthanum phosphonate chain, to share two more phosphonate oxygens, and becomes 5-coordinate. This results in the formation of an -La-O-Na-O-La- chain and a concomitant shrinking of the channels. A comparison of the monovalent metal (M(I)) ion-exchanged compounds, M(I)La(H4L), reveals that both the ionic radius and the enthalpy of hydration of the guest cation affect the equilibrium between the expanded and the contracted forms, and that the framework adapts specifically to the size of the guest cation. Furthermore the influence of the guest ion on the synthesis of NaLa(H4L) was investigated. In a screening of the synthesis parameters, Na+ was identified as a strong structure-directing agent for this framework. In addition, a series of compounds MLa(H4L) with M = Li+, Na+, K+, NH4+ and Rb+ were prepared by synthesis or ion exchange and characterized using X-ray powder diffraction, elemental analysis and scanning electron microscopy. Sorption of N2, Kr and H2O in these compounds revealed a preference of the network for water molecules. Furthermore a strong influence of the guest ions on the shape of the water sorption isotherms could be observed. The isotherms of LiLa(H4L), NaLa(H4L) and KLa(H4L) show one distinctive step of adsorption that can be correlated with the expansion of the flexible framework upon hydration. The required partial pressure for the pore expansion depends on the incorporated guest ion and increases with the decreasing hydration enthalpy form Li+ to K+.

This work is focused on the investigation of synthesis conditions for the direct growth of metal-organic frameworks (MOFs) on self-assembled monolayers (SAMs) used for surface functionalization. The characterization of the surface-grown crystals is a central part of this thesis, in order to learn more about the mechanism of MOF crystallization and the interesting properties of this class of materials leading to future applications. The tuneable oriented growth of thin films of the porous MOF HKUST-1 (Cu3(C9H3O6)2(H2O)3•xH2O) on different functionalized SAMs is demonstrated. Films grown on carboxylate-terminated SAMs are highly oriented along the [100] direction, while alcohol-terminated surfaces induce a completely different orientation along the [111] direction. Homogeneous but less oriented thin films are also obtained on methyl-terminated SAMs. A combination of X-ray diffraction and scanning electron microscopy was used to study the film growth, including the morphological evolution of the crystals on the SAMs. In situ atomic force microscopy was used to directly investigate the growth processes of the oriented MOF HKUST-1 grown on SAMs on gold substrates. This approach provides direct evidence for a layer-by-layer mechanism of the constituent 1.5 nm d111 crystal spacing step, its form during growth, and the influence of the step vertex on the rate of growth. The orientation and structure of porous MOFs based on iron terephthalate can be controlled by heterogeneous nucleation on self-assembled monolayers of mercaptohexadecanoic acid (MHDA). The framework MIL-53 is the product of homogeneous nucleation, whereas in the same crystallisation solution, oriented MIL-88B grows on the functionalized gold surface. A new sample cell was developed to allow for the investigation of the structural changes of flexible, porous materials during adsorption and desorption of guest molecules. Crystals of the flexible MOF Fe-MIL-88B were investigated as bulk material as well as surface-grown, oriented crystals. We were able to follow the structural changes of the Fe-MIL-88B crystals upon ad- and desorption of water. Due to the orientation of the crystals on the gold substrates, structural changes in [001] direction could be observed. For the randomly oriented bulk crystals the structural changes in all crystallographic directions are observable and the changes of the lattice constants a and c and the cell volume could be determined quantitatively by indexing of the complete diffraction patterns. The sorption isotherms recorded with the help of the sorption@XRD method show two distinct steps of structural changes. During adsorption of water the lattice parameter c is slightly but still detectably decreased, whereas the lattice parameter a shows a prominent two step-increase resulting in an increase of the cell volume about 40 %. The conventional volumetric water sorption measurement also shows two distinct steps of the amount of adsorbed volume that can be correlated to the structural changes observed in X-ray diffraction. We have demonstrated that advantages of functionalization can also be realized in oriented film synthesis of MOFs: We have shown for the first time that functionalized MOFs can be grown on self-assembled monolayers and that a preferred orientation of the crystals is achieved. This was demonstrated for NH2-MIL-101 and to a lesser extent for NH-MIL-88B. Importantly for potential storage applications, it was also shown that the adsorption capacity of NH2-MIL-101 was not significantly reduced by the amino functionalization.
