【摘要】 本工作合成了带有偶氮苯基的乙烯基化合物MAAAB。通过与不同丙烯酸酯的共聚得到了两组含不同组成有光响应能力的共聚物。比较了含小分子偶氮苯化合物的高分子薄膜与MAAAB共聚物的光控释放小分子的能力,发现后者具有较强的光控功能。此外,还对不同高分子母体材料的分子结构,分子运动以及松弛等对所构成薄膜光控能力的影响进行了讨论。更多还原

【Abstract】 In this work, methacryloyl p-aminoazobemzene was synthesized. Two groups of copolymer which possess different compositions and photo—responsibilities were also prepared with different acrylate monemers by copolymerization. The photoresponsibility of polymer film which contains small molecule of azobenzene compound by mechanical mixing was compared with that of film of MAAAB copolymers. It was found that the photocontrolled ability for releasing small molecule form the later film was higher than that form the former. In addition, the effect of molecular structure, molecular movement and relaxation of polymeric matrix used on the photoresponsibility of films from above materials was discussed.更多还原
