摘要：
A flexible metal-organic framework of 1a Cu(FMA)(4,4’-Bpe)0.5(FMA=fumarate; 4,4’-Bpe=trans-bis-(4-pyridyl)ethylene) that exhibits guest molecule-controlled gate-opening adsorption has been reported, in which the flexible pores can be enlarged by COmolecules rather than CHand Nunder a certain gate-opening pressure. The COuptake can be sharply improved from 6.85cm~3 gat 0.60 atm to 33.7 cm~3 gat 1 atm due to the gate-opening effect, thus resulting in the notably enhanced adsorption selectivities for CO/CH(32:1, v/v) and CO/N(48:1, v/v) separations at room temperature.
