中文摘要：

借助于蒸馏降水聚合，有 polyazobenzene 的硅石混血儿粒子轰炸(PAzo@SiO2 ) microspheres 与 6-(4-methoxy-4 鈥 ?oxy 偶氮苯) 被准备己基的 methacrylate (Azo-M ) 作为单体， divinylbenzene (DVB ) 作为 cross-linker，和锝 ? 50 个 nm vinylated 大音阶的第五音胶化硅石粒子是模板。空 polyazobenzene microspheres 进一步与 HF 答案在硅石核心的选择移动以后被开发。当与 Azo-M 有关的 DVB 的内容是 20 wt% 时， acetonitrile 是 200 mL，并且聚合时间是 4.5 h，有大约 20 nm 壳的空 PAzo microspheres 成功地被制作。这些空 PAzo microspheres 优秀可逆 photoisomerization，和他们 trans-cis 异构化的一阶的率常数仅仅减少 11.8% 与偶氮苯(Homo-PAzo ) 的 homopolymer 相比。

英文摘要：

By means of distillation precipitation polymerization, the silica-hybrid particles with polyazobenzene shell （PAzo@SiO2） micro- spheres were prepared with 6-（4-methoxy-4＇-oxy-azobenzene） hexyl methacrylate （Azo-M） as monomer, divinylbenzene （DVB） as cross-linker, and -250 nm vinylated sol-gel silica particles as template. Hollow polyazobenzene microspheres were further developed after selective removal of the silica cores with HF solution. When the content of DVB related to Azo-M is 20 wt%, the acetonitrile is 200 mL, and the polymerization time is 4.5 h, the hollow PAzo microspheres with about 20 nm shell are successfully fabricated. These hollow PAzo microspheres have excellent reversible photoisomerization, and their first-order rate constant of trans-cis isomerization only decreases 11.8% compared with homopolymer of azobenzene （Homo-PAzo）.
