A new multi-functional Cu(ii)-organic framework as a platform for selective carbon dioxide chemical fixation and separation of organic dyes

Abstract

A new multi-functional metal–organic framework, {[Cu2(HL)(H2O)2]·NMP·2H2O}n (1), was assembled by employing an asymmetrical V-shaped rigid multicarboxylic acid ligand H5L (H5L = 2,4-di(2′,5′-dicarboxylphenyl)benzoic acid) with Cu(II) ions. 1 possesses a 3D pore formed by two types of intersecting 1D cuboid channels. Moreover, owing to the abundant uncoordinated carboxylate O atoms decorated in the channels and open metal centers generated by the removal of coordinated water molecules, 1 exhibits a high CO2 adsorption capacity and significantly selective capture for CO2 over CH4. Hence, further research on the chemical fixation of CO2 is implemented, which reveals excellent heterogeneous catalytic activity. In addition, 1 displays particularly selective sorption towards the rhodamine B (RB) dye. Consequently, this study may provide a facile synthetic route for the construction of multi-functional materials.
