树状大分子PAMAM与中氮茚衍生物CCA的自组装及其性能研究

Studies on the self-assemble behavior and the properties between CCA and PAMAM dendrimer

研究了树状大分子聚酰胺-胺PAMAM(1G)外围的氨基与中氮茚衍生物CCA中的羧基的自组装行为。这一自组装实现了对树状大分子PAM-AM的表面修饰,从而也实现了CCA由油相向水相的转移。水相中PAMAM的紫外吸收与荧光都明显增强,且变化的程度与CCA的浓度有直接关系的紫外与荧光监测结果,都证实这一相转移的发生。

The self-assemble behavior between the dendrimer PAMAM （1G） and the derivatives of Indolizine （CCA） were studied,which realized the peripheral modifying for the dendrimer PAMAM,and also realized the transferring of CCA from oil phase to water phase.The fluorescent intensity and the UV absorbance of the PAMAM solution are all increased with the concentration of CCA obviously,all proved the self-assemble really happened.
