A Multifunctional Cobalt (II) Metal-Organic Framework with Nanoporous Channels for Gas and Dye Absorption, and Magnetic Performance
Coordination polymer {[Co(BTIA)(H2O)0.5]·1.5CH3OH} n(Co-1) was synthesized from Co(NO3)2·6H2O and multidentate ligand 4,6-bis-(4H-1,2,4-triazol-1-yl)-isophthalic acid(H2BTIA) under solvothermal conditions. Crystal analysis found that Co-1 was a (44·62)2(416·612) 3D framework with one dimensional channels, which gives it good adsorption performance for greenhouse gas CO2 and anionic dyes CR2− and TY−. In particular for the large-size CR2−, it behaves a very fast removal rate. In addition, magnetic analysis discloses that antiferromagnetic(AF) coupling exists in binuclear cobalt unit.
