| 摘 要： | 以空心球表面负载的叔丁基过氧化氢为引发剂,通过反向原子转移自由基聚合制备了空心球-聚甲基丙烯酸甲酯杂化材料,以此为引发剂,以含有甲基丙烯酸甲酯的铽配合物为第二单体,通过原子转移自由基聚合制备了空心球-g-PMMA-b-Tb杂化材料,并用FT-IR、GPC、TG和荧光光谱等对产物进行了测试与分析。结果表明,PMMA在空心球表面的接枝率约为8%;溶液中形成的PMMA的-Mw为28800,分子量分布指数(PDI)为1.2;杂化材料在489 nm,545 nm,583 nm,621 nm左右出现了四组发射峰,分属于Tb3+的5D4→7F6、5D4→7F5、5D4→7F4和5D4→7F3跃迁;铽配合物已接枝到空心球表面,生成了具有发光性能的杂化材料。

| Abstract: | The hollow sphere-g-poly(methyl methacrylate)(hollow sphere-g-PMMA) hybrid material was prepared via reverse atom transfer radical polymerization(RATRP) using hollow sphere supported peroxides as initiator.After that,hollow sphereg-PMMA-Tb hybrid material was fabricated by atom transfer radical polymerization(ATRP) using hollow sphere-g-PMMA as macro-initiator and Tb complex(include MMA) as the second monomer.The sample was characterized by FT-IR,GPC,TG and luminescence spectroscopy respectively.The results... |
