Zirconium-based metal-organic frameworks were recently investigated as catalysts for degradation of organophosphate toxic compounds, such pesticides or chemical warfare agents. The most utilized UiO-66 is considered a stable material these applications in an aqueous environment. However, the presented results indicate that properties are changing considerably media under common conditions used degradations, and therefore its catalytic activity not related to number structural defects created...
The combination of zirconium-based MOF UiO-66 with buffered environment leads to decomposition.
The photocytotoxic activity of porphyrin-containing materials including metal-organic frameworks (MOFs) has attracted ever increasing interest. We have developed a simple synthesis hexagonal PCN-222/MOF-545 nanoparticles, which are powerful in inducing reactive oxygen species-mediated apoptosis cancer cells upon visible light irradiation. extent the cytotoxic effect well correlates with nanoparticle size and structural instability. High phototoxicity presented nanoparticles their...
A zirconium metal-organic framework (MOF) PCN-222 was postsynthetically modified with diphenylphosphinic acid, resulting in an increased stability when activated from water and 4 times higher photosensitizing properties for singlet oxygen production. The phosphinic acid did not compromise the crystallinity of MOF but made strong bonds zirconia secondary building units.
Porous metal-organic frameworks (MOFs) have excellent characteristics for the adsorptive removal of environmental pollutants. Herein, we introduce a new series highly stable MOFs constructed using Fe3+ and Al3+ metal ions bisphosphinate linkers. The isoreticular design leads to ICR-2, ICR-6, ICR-7 with honeycomb arrangement linear pores, surface areas up 1360 m2 g-1, high solvothermal stabilities. In most cases, their sorption capacity is retained even after 24 h reflux in water. choice...
Metal-organic frameworks (MOFs) are attracting increasing attention as adsorbents of contaminants emerging concern that difficult to remove by conventional processes. This paper examines how functional groups covering the pore walls phosphinate-based MOFs affect adsorption specific pharmaceutical pollutants (diclofenac, cephalexin, and sulfamethoxazole) their hydrolytic stability. New structures, isoreticular phosphinate MOF ICR-7, presented. The phenyl ring facing wall presented is modified...
The fight against pathogenic bacteria and viruses represents a challenging task requiring the development of innovative materials. design water-responsive disinfecting surfaces constitutes pertinent endeavor to limit spread infectious pathogens that strive in wet environments are often carried by droplets or aerosols biological fluids. In this context, we designed polymeric nanostructured membrane which, when contact with water, was able release elemental iodine, potent antimicrobial agent....
The stability of MOFs in aqueous environments is influenced by the linker topicity rather than connectivity. Only MIP-200 survives alkaline environment.
The design and preparation of highly active heterogeneous palladium catalysts is attracting ever‐increasing attention. In this paper, we report on the self‐assembly centers an octahedral molybdenum cluster complex bearing phosphine terminal ligands. This leads to a coordination polymer exhibiting high catalytic activity in Suzuki–Miyaura cross‐coupling reaction. achieved turnover number 15800 reaction deactivated aryl bromides with phenylboronic acid. Because metal clusters represent rare...
The unprecedented co-thermolysis of decaborane(14) (nido-B10 H14 ) and toluene results in a novel porous material (that we have named "activated borane") containing micropores between 1.0 1.5 nm diameter specific surface area 774 m2 g-1 (Ar, 87 K) that is thermally stable up to 1000 °C. Solid state 1 H, 11 B 13 C MAS NMR, UV-vis IR spectroscopies suggest an amorphous structure borane clusters interconnected by moieties ratio about three molecules for every cluster. In addition, the contains...
The first Ce(III)-based coordination polymer ICR-9 (ICR stands for Inorganic Chemistry Řež), with the formula Ce2(C8H10P2O4)3, containing ditopic phenylene-1,4-bis(methylphosphinic acid) linker, was synthetized under solvothermal conditions. crystal structure, solved using electron diffraction tomography (EDT), revealed 2D layers of octahedrally coordinated cerium atoms attached together through O-P-O bridges. structure is nonporous, however, modification synthetic conditions led to...
Borane cluster-based porous covalent networks, named activated borane (ActB), were prepared by cothermolysis of decaborane(14) (nido-B10H14) and selected hydrocarbons (toluene, ActB-Tol; cyclohexane, ActB-cyHx; n-hexane, ActB-nHx) under anaerobic conditions. These amorphous solid powders exhibit different textural Lewis acid (LA) properties that vary depending on the nature constituent organic linker. For ActB-Tol, its LA strength even approaches commonly used molecular LA, B(C6F5)3. Most...
Metal-organic frameworks (MOFs) are attracting increasing attention as adsorbents of contaminants emerging concern which difficult to remove by conventional processes. However, common carboxylate-based MOFs suffer from low stability in water environment, limits their environmental applications. In this study, we use phosphinate-based with higher hydrolytic and focus on the influence functional groups covering pore walls adsorption pharmaceutical pollutants present – diclofenac, cephalexin...
