One of the reasons for the enormous interest in the class of porous metal organic frameworks (MOFs) is their structural flexibility, which is in contrast to the rather rigid zeolites. Kitagawa et al. have coined the term “third generation porous coordination polymers” for systems that undergo structural transformations in response to external stimuli, such as guest adsorption. One of the most d...

Metal-organic frameworks (MOFs) imply an appealing source of photocatalysts as they combine porosity with tailorable electronic properties and surface chemistry. Herein, we report a series unprecedented metal-organic aerogels (MOAs) comprised by Ti(IV) oxo-clusters aromatic dicarboxylic linkers alternative to microporous MIL-125 MIL-125-NH2 MOFs. Discrete titanium polymerized upon the addition ...

Ce-doped MIL-125-NH2 photocatalysts (Ce/TiMOFs) were synthesized by a facile impregnation-coordination method, during which the doped Ce species could not only extend visible-light absorption edge but also provide new reactive sites for promoting charge transfer and selectivity of two-electron O2 reduction. The optimal Ce/TiMOFs-0.010 achieved rate H2O2 yield 2464 μM h-1 g-1 with ∼3.4-fold impr...

A novel NH 2 -MIL-53(Fe)/AgSCN composite photocatalyst was successfully prepared by a one-step chemical precipitation method, the show high photocatalytic activity for antibiotics degradation and H evolution under visible light irradiation.

Metal–organic frameworks (MOFs) are among the most sophisticated nanostructured solids: they often possess high surface areas and pore volumes, with the possibility of finetuning their chemical environment by either selecting the appropriate building blocks or by postsynthetic functionalization. For many frameworks, flexibility of the lattice allows them to undergo a significant transformation ...

Postsynthetic modification of metal-organic frameworks (MOFs) has proven a hugely powerful tool to tune physical properties and introduce functionality, by exploiting reactive sites on both the MOF linkers their...

The functionalised metal-organic framework MIL-101(Cr)-NH(2), containing 2-aminobenzene-1,4-dicarboxylate as the linker, has been synthesised. A new tandem post-synthetic modification strategy involving diazotisation as the first step has been developed and used to introduce halo- and azo dye-functional groups into the pores.

A mixed-metal metal-organic framework, (Al,Ga)-MIL-53, synthesised by post-synthetic ion exchange has been investigated using solid-state nuclear magnetic resonance (NMR) spectroscopy, microscopy and energy dispersive X-ray (EDX) spectroscopy. 17O enrichment during...
