Facile Fabrication and Enhanced Photoluminescence Property of Zn(II) Coordination Polymers with 2,2'-biquinoline-4,4'-dicarboxylic Acid
Abstract:
With 2,2'-biquinoline-4,4'-dicarboxylic acid disodium salt (BCA) and Zn (CH3COO)2·2H2O as starting materials, a sheaflike Zn (II)-2,2'-biquinoline-4,4'-dicarboxylic acid disodium salt coordination polymers (Zn-BCA CPs) has been successfully synthesized through a simple and mild one-step process in aqueous solution at room temperature. The effects of reactant molar ratio, temperature and reaction time on the morphology of the coordination polymers have also been examined. It was found that the Zn-BCA CPs showed an greatly enhanced blue photoluminescence emission compared with Zn-free BCA.
