Stabilization of a highly porous metal–organic framework utilizing a carborane-based linker

Abstract

The first tritopic carborane-based linker, H3BCA (C15B24O6H30), based on closo-1,10-C2B8H10, has been synthesized and incorporated into a metal-organic framework (MOF), NU-700 (Cu3(BCA)2). In contrast to the analogous MOF-143, NU-700 can be activated with retention of porosity, yielding a BET surface area of 1870 m(2) g(-1).

10-Vertex closo-carborane: a unique ligand platform for porous coordination polymers

“…3 has a very open framework structure with a calculated porosity of ∼3700 m 2 g −1 for the hypothetical solvent-free 3a, 17 potentially exceeding even the value for the best linear spacer-based carborane-containing (however, mostly noncarborane) NU-135 PCP which is 2700 m 2 g −1 (2530 m 2 g −1 is the experimentally proven value). 13 Unfortunately, direct activation without solvent exchange is not possible for copperbased PCPs containing DMF due to reductive degradation; hence, milder post-exchange super critical drying 23 is to be implemented.…”

Rational design of carborane-based Cu2-paddle wheel coordination polymers for increased hydrolytic stability

“…[39][40][41][42] In pursuit of synthesizing water-resistant MOFs, we are working on the design and preparation of carborane based ligands. [43][44][45][46][47][48] Incorporation of such ligands into CPs or MOFs is known to increase their thermal [49][50][51][52][53][54][55][56] and hydrolytic-stability. 27,[57][58][59][60] For example, we have recently reported the most stable Cu-paddle wheel MOF in the literature against water.…”

Advances in antitumor nanomedicine based on functional metal–organic frameworks beyond drug carriers

“…Nanoscale metal-organic frameworks (MOFs), also known as coordination polymers or porous coordination networks, are formed by bridging metal ions or metallic clusters via organic ligands. 1 MOFs have attracted considerable interest due to their unique properties, including large surface area, easily adjustable pore size and a stable pore structure, [2][3][4] high drug loading capacity and excellent biocompatibility. [5][6][7] The application of MOFs has been investigated in various fields, for example, gas a School of Environmental and Chemical Engineering, Shanghai University, 99 Shangda Road, Shanghai 200444, China.…”
