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
Homochiral metal–organic frameworks (HMOFs) are efficient materials for enantioselective adsorption. However, the combination of size selectivity and enantioselectivity is still a major challenge in the field of HMOFs. Herein, two enantiomorphic HMOFs built from predesigned proline‐derived ligands are presented. Both of them show multiple homochiral features: they contain four different helical chains

By employment of predesigned proline derivative ligands ((R)-PIA and (S)-PIA) to assemble with bipy and Cd2+ ion, a pair of porous homochiral metal–organic frameworks (HMOFs) with a wavy Cd-PIA layer has been synthesized.
