Scorpionate‐Type Coordination in MFU‐4l Metal–Organic Frameworks: Small‐Molecule Binding and Activation upon the Thermally Activated Formation of Open Metal Sites

Abstract

On again, off again: Coordinatively unsaturated metal centers, such as zinc(II) hydride and copper(I), were generated within the MFU-4l structure (see picture). Cu Bond after bond: A series of polychalcogenotrimethylsilane complexes Ar(CH 2 ESiMe 3 ) n , (Ar = aryl; E = S, Se; n = 2, 3, and 4) have been prepared that incorporate a large number of reactive ÀESiMe 3 moieties onto an organic molecular framework (see figure). They are shown to be convenient reagents for the preparation of the polyferrocenylseleno-and thioesters from ferrocenoyl chloride. Study history, study history: Visible-light-driven Co 3 O 4 spinel water oxidation catalysts (WOCs) were hydrothermally prepared and investigated with respect to the influence of preparative history on the catalytic activity. We present a counterintuitive design trend: crystallinity and valence states are more important for WOC performance than surface area. New "top down" and "bottom up" strategies for Co 3 O 4 WOC optimization are proposed.Chem. Asian J.

Selective nitrogen adsorption via backbonding in a metal–organic framework with exposed vanadium sites

“…Although some metal-organic frameworks are known to contain metal centers with the appropriate electronic configuration for π-backbonding, the lack of diffuse orbitals or the requisite molecular orbital energies has prevented realization of an effective adsorbent for π-acidic gases 17,18 .…”

Negative cooperativity upon hydrogen bond-stabilized O2 adsorption in a redox-active metal–organic framework

“…The development of a metal-organic framework capable of cooperative O 2 adsorption could be advantageous for a number of applications in industry, including energy-efficient O 2 production 11,12 , O 2 storage [13][14][15] , and catalysis 16,17 . Iron- 18,19 , chromium- 20,21 , manganese- 22 , copper- 23 , and cobalt-based 24,25 frameworks have previously been shown to bind O 2 via reversible reduction upon metal coordination, but the poor chemical stability of many of these materials to O 2 limits their cyclable capacity under ambient conditions. In the search for improved, cooperative adsorbents for O 2 capture, the active sites of proteins such as hemoglobin, hemerythrin, and hemocyanin can serve as sources of inspiration.…”

Efficient purification of ethene by an ethane-trapping metal-organic framework

“…Because unsaturated hydrocarbons like to coordinate with metal ions, C 2 H 4 can be selectively bound and separated from its saturated counterpart C 2 H 6 (refs 12 , 13 , 14 , 15 , 16 ). Compared with other types of porous materials, porous metal-organic frameworks (MOFs) are unique for their diversified/designable framework structures and pore surfaces, including the ease of introducing open metal sites (OMSs), which have shown great potentials for C 2 H 4 /C 2 H 6 separation 17 18 19 20 21 22 .…”
