title: Self-assembly of homochiral porous solids based on 1D cadmium(II) coordination polymers.
abstract: A family of homochiral 1D cadmium(II) coordination polymers based on the (S)-2,2'-dimethoxy-1,1'-binaphthyl-3,3'-bis(4-vinylpyridine) (L) bridging ligand were synthesized from the same building blocks under slightly different conditions, and characterized by single-crystal X-ray crystallography. While [CdL(DMF)4](ClO4)2 x EtOH x 0.5H2O (1) adopts a 1D zigzag chain structure, [CdL2(ClO4)2] x 3EtOH x H2O (2) and [CdL2(ClO4)(H2O)] (ClO4) x 1.5(o-C6H4Cl2) x 3EtOH x 6H2O (3) both exhibit 1D polymeric structures that are built from 38-membered macrocycles. These 1D coordination polymers further pack into chiral porous frameworks via pi...pi interactions with a large percentage of void spaces that are occupied by solvent molecules and counterions.
