A microporous metal-organic framework with butynelene functionality for selective gas sorption

A microporous metal-organic framework with butynelene groups, {[Cu2(BBTC)(H2O)2]·2DMSO·4H2O}n, exhibits higher gas selective sorption towards C2H2/CH4 and CO2/CH4 at room temperature with a selectivity of 5.7 and 4.1, respectively.
