Hierarchical Assembly of Homochiral Porous Solids Using Coordination and Hydrogen Bonds

A family of homochiral metal carboxylate coordination polymers
have been synthesized by treating 2,2‘-dihydroxy-1,1‘-binaphthalene-6,6‘-dicarboxylic acid (H2BDA) with metal salts at elevated
temperatures. BDA ligands link adjacent metal centers to form 1D
coordination polymeric chains using the carboxylate functionality,
while the hydroxyl groups of BDA ligands form H-bonds with
carboxylate oxygen atoms to link 1D coordination polymeric chains
into open frameworks of higher dimensionality. We also present
evidence for the important role played by H-bonds in the
stabilization of open framework structures which allows for the
hierarchical assembly of chiral porous solids.
