Abstract
A pair of homochiral metal–organic frameworks based on proline derivative ligands ((S)-H3PIA and (R)-H3PIA), namely [Cd3Na((S)-PIA)2(CH3CO2) (H2O)6]·2H2O (1-L) and [Cd3Na((R)-PIA)2(CH3CO2) (H2O)6]·2H2O (1-D), have been synthesized. Crystallographic analysis indicates complexes 1-L and 1-D contain interesting infinite hetrometallic and homochiral helical chains. Some physical characteristics, such as solid-state circular dichroism (CD), thermal stabilities and photoluminescent properties were also investigated. Our results highlight a feasible synthesis method to construct functional HMOFs from proline derivative ligands and heterometal ions.
