摘　　要：以空心球表面负载的偶氮基团为引发剂,以苯乙烯和对叠氮甲基苯乙烯为单体,通过反向碘原子转移自由基聚合(RITP)制备了空心球-g-苯乙烯-co-对叠氮甲基苯乙烯(Hollow sphere-g-PS-co-PVBA)杂化材料,再通过N-炔丙基咔唑与空心球-g-PS-co-PVBA的"Click"反应,得到具有光功能的空心球-g-PS-co-PVBPC有机-无机杂化材料。并用扫描电镜(SEM)、红外光谱(FT-IR)、热重分析(TG)、核磁共振(1H-NMR)和荧光光谱等对产物进行了测试和分析。结果表明,空心球表面接枝了苯乙烯和对叠氮甲基苯乙烯的无规共聚物,接枝率约为36%;聚合体系按照反向碘原子转移自由基聚合(RITP)机理进行;空心球-g-PS-co-PVBPC杂化材料在360 nm附近出现了强烈的荧光发射峰,说明点击反应的成功进行。The hollow sphere-g-poly（styrene）-co-poly（4-vinylbenzyl azide） （hollow sphere-g-PS-co-PVBA） hybrid material was prepared via reverse iodine transfer polymerization （RITP） using hollow sphere supported azo group as initiator, styrene and 4-vinylbenzyl azide as monomers. After that, hollow sphere-g-PS-co-PVBPC optical-functional organic-inorganic hybrid material was fabricated by “Click” reaction of N-propargyl-carbazole and hollow sphere-g- PS-co-PVBA. The samples were characterized by FT-IR, SEM, TG, 1H-NMR and luminescence spectroscopy. The results show that the copolymer of styrene and 4-vinylbenzyl azide has grafted on the hollow sphere surface and the graft ratio is about 36%. The polymerization is carried out via reverse iodine transfer polymerization （RITP）. In emission spectrum of hollow sphere-g-PS-co-PVBPC hybrid material, there is a strong characteristic fluorescence emission bands at about 360 nm, proving the success of the “Click” reaction.
