family of amphiphiles, derived from a rigid dicarboxylic acid headgroup unit of unusual topology, has been synthesized. The aggregation of these molecules in aqueous solution has been examined by 1 H NMR and dye solubilization methods. Two modes of aggregation appear to be operative within this group of amphiphiles, one determined by the headgroup and the other determined by the flexible tail. The
已经合成了一个新的两亲物家族,它们源自具有不寻常拓扑结构的刚性二羧酸头基单元。这些分子在水溶液中的聚集已经通过 1 H NMR 和染料溶解方法进行了检查。两种聚集模式似乎在这组两亲分子中起作用,一种由头部决定,另一种由柔性尾部决定。当尾部很短或不存在时,前一种模式占优势,当尾部含有六个或更多非极性原子时,后者占优势。后一种模式看似是典型的胶束化过程,但前者的合作性较差
