A new methyl-embedded (3,36)-connected txt-type metal–organic framework exhibiting high H2 adsorption property†
Abstract
A new methyl-embedded (3,36)-connected txt-type metal–organic framework, {Cu2(DCPEMP)·H2O}n (NJFU-4, H4DCPEMP = 3,5-bis(3,5-dicarboxylphenylethynyl)-4-methylpyridine), was solvothermally synthesized and structurally characterized, which exhibits a BET surface area of 2160 m2 g−1, high stability and high H2 uptake capacity (2.61 wt% at 1 bar and 77 K).
