【摘要】 通过UV vis,1HNMR和TEM等方法研究了 [溴化十烷基三甲铵 (DTAB)与N (4 癸氧基 2 羟基苄基 )甘氨酸(C10 HG) ]正负离子表面活性剂混合体系中的正离子 π相互作用 .实验结果表明在聚集体中DTAB分子处于C10 HG的芳环平面上方 ,二者之间存在着阳离子 π相互作用 ,该相互作用有利于囊泡的形成更多还原

【Abstract】 Cation-π interaction in mixed system of catanionic surfactant [decyltrimethylammonium bromide (DTAB)-N-(4-decyloxy-2-hydroxy-benzylidene)glycine (C 10HG)] was investigated by the methods of UV-vis, 1H NMR and TEM. The experimental results show that DTAB is on the top of C 10HG’s aromatic ring and there exists cation-π interaction between them. The existence of the interaction promotes the formation of vesicles.更多还原
