Herein, a new group of visible light photocatalysts is described. Iron(III) oxides could be promising because their small band gap enabling excitation. However, the high electron-hole recombination rate limits yield highly oxidizing species. This can overcome by reducing particle dimensions. In this study, metal-organic frameworks (MOFs), containing Fe3-μ3-oxo clusters, are proposed as photocatalysts. Their photocatalytic performance tested and proven via degradation Rhodamine 6G in aqueous...
Electrochemical film growth of metal-organic frameworks (MOFs) enables the self-completing densely packed crystallite layers in a patterned fashion. Coatings produced this manner might prove useful integration MOF materials with devices such as sensors, concept that is illustrated by monitoring water adsorption.
After controlled pretreatment, some Zr-terephthalate metal-organic frameworks are highly selective catalysts for the cross-aldol condensation between benzaldehyde and heptanal. The proximity of Lewis acid base sites in amino-functionalized UiO-66(NH(2)) material further raises reaction yields.
Functionalized linkers can greatly increase the activity of metal-organic framework (MOF) catalysts with coordinatively unsaturated sites. A clear linear free-energy relationship (LFER) was found between Hammett σ(m) values linker substituents X and rate k(X) a carbonyl-ene reaction. This is first LFER ever observed for MOF catalysts. 56-fold in when substituent nitro group.
The ability of metal-organic frameworks (MOFs) to gelate under specific synthetic conditions opens up new opportunities in the preparation and shaping hierarchically porous MOF monoliths, which could be directly implemented for catalytic adsorptive applications. In this work, we present first examples xero- or aerogel monoliths consisting solely nanoparticles several prototypical Zr4+-based MOFs: UiO-66-X (X = H, NH2, NO2, (OH)2), UiO-67, MOF-801, MOF-808 NU-1000. High reactant water...
Here we describe the synthesis and postsynthetic modification of stable β-ketoenamine TpBD(NH2)2 covalent organic framework (COF), having primary amine groups integrated into pore walls. For this purpose initially synthesized nitro version COF, TpBD(NO2)2. Afterward, TpBD(NO2)2 was reduced to afford desired functionality. We demonstrate accessibility robustness by a second step, aminolysis acetic anhydride, obtain corresponding amide form TpBD(NHCOCH3)2. Taking advantage high stability these...
Replacing conventional solvents by ionic liquids is often suggested as a possible route to greener industrial processes. However, are typically petroleum-derived. This critical perspective discusses the syntheses, applications and limitations of biobased synthesized from amino acids, carbohydrates, lignin other renewable sources. The practical aspects applying such in lignocellulose processing, reaction solvent, organocatalyst or metal extraction medium highlighted.
Film deposition is an enabling technology for integration of novel functional materials into real-world practical applications. We report both the anodic and cathodic electrochemical film UiO-66, a prototype highly stable, zirconium-based metal–organic frameworks, using zirconium foil as only metal source. The fundamentally different formation mechanisms at cathode anode result in significantly coating adhesion strength, mainly due to oxide serving bridging layer anode. patterned capability...
Porosity and surface area analysis play a prominent role in modern materials science. At the heart of this sits Brunauer-Emmett-Teller (BET) theory, which has been remarkably successful contribution to field The BET method was developed 1930s for open surfaces but is now most widely used metric estimation areas micro- mesoporous materials. Despite its widespread use, calculation causes spread reported areas, resulting reproducibility problems both academia industry. To prove this, analysis,...
Integrating metal–organic frameworks (MOFs) into microfabrication processes will benefit from controlled vapor-phase deposition techniques. This study presents a molecular layer method that enables area-selective and oriented growth of zeolitic imidazolate framework-8 (ZIF-8) films. Substrates functionalized with self-assembled monolayers (SAMs) different end groups (alkyl, phenyl, hydroxyl, carboxyl, amine, imidazole) allow tuning the degree crystallographic orientation in resulting MOF...
Processing metal–organic frameworks with spatial and temporal control over crystal formation will increase the applicability of these highly porous materials. By exploiting solvent effects, stable synthesis solutions can be obtained, which used in combination soft lithographic techniques to deposit oriented crystals patterns by situ crystallization (see figure).

Shields up! Post-synthetic modification of the secondary building units in metal-organic framework UiO-66 (Zr6O4(OH)4(O2CR)12) by dehydration and subsequent grafting LiOtBu yields a solid Li(+) electrolyte with conductivity 1.8×10(-5) S cm(-1) at 293 K. As leads to screening anionic charge, activation energy for ionic conduction is significantly lower than when introduced through deprotonation.
The effect of a post-synthetic acid treatment on the catalytic performance MOFs is evaluated for MIL-100(Fe), an iron-benzenetricarboxylate. acid-treated frameworks are structurally robust as no differences have been found in XRD patterns after treatment. Porosity gradually decreases, most probably consequence anions remaining charged frameworks. Monitoring modification by reactions which outcome depends properties catalyst suggests presence two types active sites, with weak Brönsted sites...
