Abstract
A series of new polymers with conjugated poly(p-phenylene vinylene) units and non-conjugated poly(p-xylylene) units containing vinyl and carboxyl groups were synthesized. The monodisperse CdSe/ZnS nanocrystals with a red light emission were prepared by using the phosphine-free precursors. A novel fluorescent polymer and 5-(2-methacryloylethyloxymethyl)-8-quinolinol were dispersed in vinyl monomers containing CdSe/ZnS NCs to successfully fabricate transparent bulk nanocomposites by in situ polymerization. The 5-(2-methacryloylethyloxymethyl)-8-quinolinol molecules can be coordinated to the surface of CdSe/ZnS nanocrystals to form a metalloquinolate with green light emission at about 500 nm, while the red light emission of nanocrystals remained after the polymerization process. The efficient white light emitting polymer nanocomposites with color coordinates (0.32, 0.34) can be obtained when the weight ratio of nanocrystals to 5-(2-methacryloylethyloxymethyl)-8-quinolinol is 10:1. A charge transfer from the photoexcited metalloquinolates to the nanocrystals was observed in the system.
