含氟偶氮苯光响应性聚合物的合成及性能
Synthesis and Properties of Photoresponsive Polymer Materials Containing Fluoro-Azobenzene
摘要
Abstract
Decafluoroazobenzene was synthesized with satisfied yield via 1 ,2,3 ,4,5-pentafluoroaniline as the starting material and FeSO4 ? 7H2O supported KMnO4 as the oxidant. Decafluoroazobenzene was hydrolyzed in f-BuOH in the presence of KOH, and then methacrylated with methacrylic chloride. Finally, a photore- sponsive functional monomer, ( 4-methacryloyloxy) nonafluoroazobenzene ( MANFAB ) , was obtained. The structure of MANFAB was confirmed by GC-MS, elemental analysis, and NMR. The photoresponsive proper ties of MANFAB were studied by UV-Vis. Photoresponsive cross-linked polymer containing fluoro-azobenzene were prepared by radical polymerization with trimethylolpropanetrimethylacrylate as the cross-linker, (4-methacryloyloxy)nonafluoroazobenzene as the functional monomer, and A1BN as the initiator. After polymerization, the photoisomerizations of fluoro-azobenzene chromophore were retained. And the photoresponsive properties of the polymer materials were also studied by UV-Vis spectra.关键词
