Formation of a metal-organic framework with high gas uptakes based upon amino-decorated polyhedral cages

摘要

A new three-dimensional metal-organic framework 1 was solvothermally synthesized by 1,2,4-triazole and 2-aminoterephthalic acid, and structurally characterized. 1 features a three-dimensional structure with one-dimensional pores along the c axis of 6 x 6 angstrom(2). Activated 1 exhibits an H-2 uptake capacity at 77 K. Importantly, it shows excellent enthalpy of CO2 (35 kJ mol(-1)) and methane (24 kJ mol(-1)), compared to previous porous materials.
