Abstract:The amphipathic poly(N-phenylmaleimide)-b-poly(4-vinylpyridine)-zinc acetate(PNPMI-b-P4VP-Zn(Ac)2) complex has been synthesized by reversible addition fragmentation chain transfer(RAFT) polymerization,using N-phenylmaleimide and 4-vinylpyridine-zinc acetate(4VP-Zn(Ac)2) as monomers.The products as prepared have been characterized by nuclear magnetic resonance spectrum(NMR),X-ray diffraction(XRD),scanning electron microscope(SEM) and transmission electron microscope(TEM).The ZnS mass fraction increases from 8.2% to 12.6% with the block copolymerization time increasing from 1h to 30h.The particle size of ZnS also increases from 3 nm to 200 nm,accompanied with the crystal style conversion of ZnS from cubic to hexagonal.The photoluminescence(PL) intensity of PNPMI-b-P4VP decreases with the increasing block copolymerization time,however,the PL intensity of ZnS increases.Results show that,the fluorescence resonance energy transfer properties between PNPMI-b-P4VP and ZnS are controllable by RAFT method.The PNPMI-b-P4VP-ZnS FRET probe shows a potential application in the biologic field.
Keywords:RAFT  poly(N-phenylmaleimide)-b-poly(4-vinylpyridine)  nanocomposite  photoluminescence
