Abstract

Abstract : The first homochiral metal–organic framework (MOF) based on an atropisomeric 4, 4′-bipyridine ligand is described. Abstract : Coordination polymers (CP) assembled from 3, 3′, 5, 5′-tetrasubstituted 4, 4′-bipyridines and silver salts have been prepared and characterized by X-ray diffraction. Silver-CPs based on infinite Ag–bipyridine chains were obtained where one or two halogen atoms strongly interacted with Ag. A homochiral MOF was also prepared using the enantiopure 3, 3′-dibromo-5, 5′-bis(4-methoxyphenyl)-4, 4′-bipyridine as ligand, while its racemic form only formed a compact CP. Preliminary applications showed that the homochiral network is able to recognize the enantiomers of rac -styrene oxide and to control the cytotoxicity level of the Ag-based MOF toward a cell line derived from adult human skin (HaCaT).
