Chiral metal-organic frameworks(MOFs),as a novel type of porous material with many properties such as large surface area,diverse structure,adjustable pore size and good chemical stability,have aroused much attention in the field of chromatographic separation. In this paper,a homochiral MOF [Cu_3(HL)_2(L)_2(bpy)_3]·4H_2O with 2 D chiral network was synthesized through the reaction of two kinds of ligands((1 R,2 R)-1,2-cyclohexanedicarboxylic acid(H2 L) and 4,4'-bipyridine(bpy)) with copper ion via a solvothe...
