两种光学活性的偶氮聚电解质聚{丙烯酸-2-[4-(4′-乙氧基苯基偶氮苯氧基)]己酯-共-丙烯酰胺}(P(EAPHA-co-AAm))和聚{丙烯酸-2-[4-(4′-乙氧基苯基偶氮苯氧基)]己酯-共-丙烯酸}(P(EAPHA-co-AA))在pH=7的水溶液中存在静电和氢键作用.将它们分别与荧光标记物α-环糊精-罗丹明B(α-CD-RhB)通过主-客体作用形成“即插即用”(Plug and Play,PnP)的偶氮苯/环糊精聚合物模板.然后通过层层自组装技术(Layer-by-Layer self-assembletechnique,LbL),将两种聚合物模板交替组装到氨基修饰的石英片上获得自组装多层膜光控药物释放系统.实验结果表明,通过紫外和可见光的交替照射,光学活性多层膜能够在20分钟内快速完成药物模板分子的可逆释放和吸附;经过8次循环后,对α-CD-RhB的固定率仍能达到96.6％以上.同时,通过紫外-可见光光度计对多层膜形成过程进行监控,发现药物分子的吸收强度随着偶数层的增加而增加,而在奇数层组装时则发生脱附现象.
