Synthesis and Characterization of a Water-soluble Hyperbranched Poly(p-phenylene vinylene) (WHPV)

A water-soluble hyperbranched poly(p-phenylene vinylene)(WHPV) was synthesized through Wittig reaction. The polymer bore a -SO 3 -group in each connecting module, which makes the polymer water-soluble. The fluorescence emission band of the resulting polymer is located around 460 nm. Molecular dynamics simulation shows that the branches of the WHPV may construct many cavities and the -SO 3 -groups are located around the cavity walls. The interaction between WHPV and CdS nanoparticles should be fairly strong and the composite of WHPV with CdS nanoparticles can be obtained.
