Abstract:

Using lactic acid derivatives (R),(S)-4-(1-carboxyethoxy)benzoic acid[(R)-H2CBA and (S)-H2CBA)] and 1,4-di(1H-imidazol-1-yl)benzene(1,4-DIB) ligand to assemble with Ni2+ ions, a pair of novel 4-connected homochiral metal-organic frameworks, [Ni2((R)-CBA)2(1,4-DIB)3(H2O)2xH2O(1-D) and [Ni2((S)-CBA)2(1,4-DIB)3(H2O)2] ·xH2O(1-L) have been synthesized under hydrothermal conditions. Complexes 1-D and 1-L feature 2-fold interpenetration structure, containing two kinds of helical chains constructed by achiral 1, 4-DIB ligands and Ni2+ ions. Moreover, powder X-ray diffraction(PXRD), thermogrtavimetric analysis(TGA) and solid-state circular dichroism(CD) techniques were also applied to investigate the properties of the complexes..

Key words: Homochiral metal-organic framework, 4-Connected net, 2-Fold interpenetration, Helical chain
