Fine tuning of gold electronic structure by IRMOF post-synthetic modification

In this communication, we present a strategy to fine-tune the electronic structure of gold atoms by means of post-synthetic modification of IRMOF-3 (iso-reticular metal organic framework-3) with salicylaldehyde derivatives. Changes in the electronic structure of gold were predicted by theoretical calculations and determined by resonant inelastic X-ray scattering (RIXS) at the gold L3 edge. Modification of the coordinating group affected the relative HOMO and LUMO energy levels, resulting in a change of the HOMO-LUMO gap. The ability to fine tune electronic structure may lead to tailoring of the catalytic performance and material electronics states. The Royal Society of Chemistry 2013.

Post modification of zinc based coordination polymer to prepare Zn-Mo-ICP nanoparticles as efficient self-supported catalyst for olefin epoxidation

Preparation, characterization, and catalytic properties of bimetallic coordination polymer constructed from 2-aminoterephthalic acid as linker, zinc cations as node, and cis-dioxo molybdenum units as catalytic active sites are reported via two pathways. Molybdenum centers were placed in N,O positions created by condensation reaction of 2-aminoterephthalic acid with salicylaldehyde while zinc cations coordinated via carboxylic acid groups of linker to achieve infinite chains of metalo-ligand. The obtained coordination polymer was fully characterized and its catalytic properties in the epoxidation of olefins with tert-butyl hydroperoxide (TBHP) described. In comparison with previously reported heterogenized molybdenum catalysts, this new coordination polymer exhibited good conversion as well as high selectivity in the epoxidation of olefins. The catalyst is stable under ambient conditions and could be reused as active catalyst for at least five times.

Framework functionalisation triggers metal complex binding

Post-synthetic derivatisation of a porous material produces a functionalized material that binds the metal complex V(O)acac2, in contrast to the unfunctionalized precursor, which is inactive for complex binding. The Royal Society of Chemistry.

Spray drying for making covalent chemistry: Postsynthetic modification of metal-organic frameworks

Covalent postsynthetic modification (PSM) of metal-organic frameworks (MOFs) has attracted much attention due to the possibility of tailoring the properties of these porous materials. Schiff-base condensation betwecn an amine and an aldehyde is one of the most common reactions in the PSM of MOFs. Here, we report the use of the spray drying technique to perform this class of organic reactions, either betwecn discrete organic molecules or on the pore surfaces of MOFs, in a very fast (1-2 s) and continuous way. Using spray drying, we show the PSM of two MOFs, the amine-terminated UiO-66-NH2 and the aldehyde-terminated ZIF-90, achieving conversion efficiencies up to 20 and 42%, respectively. Moreover, we demonstrate that it can also be used to postsynthetically cross-link the aldehyde groups of ZIF-90 using a diamine molecule with a conversion efficiency of 70%.

AIEgen modulated per-functionalized flower-like IRMOF-3 frameworks with tunable light emission and excellent sensing properties

A series of functional IRMOF-3 frameworks with solid-state luminescence and tuneable light emission (from 490 to 608 nm) have been synthesized by per-functionalizing AIE-active Schiff-bases with zinc. These precursor AIE-active ligands endowed the functional frameworks with boosted fluorescence emission efficiencies (from 0.16% to 1.03%). IRMOF-3-hrevealed a flower-like morphology attributed to the formation of J-aggregates, and could be used as a fluorescent probe for sensitive detection of copper(ii) (135 pM) and thiols (subnanomole).
