Enhanced C0_2 Binding Affinity of a High-Uptake rht-Type Metal-Organic Framework Decorated with Acylamide Groups

摘要

An rht-type metal-organic framework (MOF) prepared from M_2(carboxylate)_4 (M = Cu, Co) paddlewheel clusters and a flexible C3-symmetric hexacarboxylate ligand with acylamide groups exhibits larger CO_2 uptake, an enhanced heat of adsorption, and higher selectivity toward CO_2/N_2 in comparison with what was previously observed for an analogous MOF with alkyne groups.
