Islam, Mai Binh, Do Kim, Kwon Lim] Poly(N-vinylcarbazole) (PVK) grafted ZnS quantum dots (QDs) (ZnS-g-PVK) involving covalent bonds between the inorganic and organic segments were synthesized by a facile ultrasonic irradiation technique. The hydroxyl group-coated ZnS QDs were first prepared using zinc chloride and sodium sulfide in the presence of 2-mercaptoethanol. The ZnS QDs were then coupled with the reversible addition-fragmentation chain transfer agent 2-(dodecylthiocarbonothioylthio)-2-methylpropionic acid (DTMPA) by condensation reaction. Subsequently, the surface initiated graft polymerization of N-vinylcarbazole from the DTMPA functionalized ZnS QDs surface was accomplished upon exposure to ultrasonic irradiation to deliver covalently attached PVK with ZnS QDs. The chemical structure of the nanocomposites was investigated by FT-IR and XPS analyses. Molecular weight and polydispersity index of the cleaved PVK from the nanocomposites were determined by GPC. The physical structure and thermal properties of the nanocomposites were studied by XRD and TGA. TEM images suggested that ZnS QDs were uniformly distributed in PVK matrices. The nanocomposites showed good optical properties as studied by photoluminescence spectroscopy.
