Novel layered crystalline zinc poly(styrene-phenylvinyl phosphonate)-phosphate synthesized by a simple route in a THF–water medium

Abstract

A novel type of organic polymer–inorganic hybrid material layered crystalline zinc poly(styrene-phenylvinyl phosphonate)-phosphate (ZnPSPPP) was prepared by the reaction of styrene-phenylvinyl phosphonic acid copolymer with zinc acetate dihydrate and sodium dihydrogen phosphate. The ZnPSPPP were characterized by FT-IR, diffusion reflection UV-Vis, AAS, N₂ volumetric adsorption, SEM, TEM and TG. Unexpectedly, the layered crystalline ZnPSPPP obtained was not synthesized with traditional methods as other zinc phosphonates, but with the ones for amorphous reactions without addition of any template. It can be deduced that the layered crystalline ZnPSPPP could have potential applications for heterogeneous catalyst supports.
