摘要： 以酰氯或酸酐与N-(3′-氨苯基)氮杂冠醚反应合成了一系列含长脂链基团的单氮杂冠醚两亲分子。电镜观测结果表明:系列两亲分子在稀溶液中均能自组织稳定的以双分子膜为基本结构的囊泡,其大小为30～150nm,泡壁厚度为5～25nm;并用UV-Vis和微量差示扫描量热研究了双分子膜中分子的聚集态和相变过程。

Abstract: Anew series of amphiphilic monoaza crown ethers which contain aliphatic amido group were synthesized by the reaction of alkyloyl halide or acidic anhydride with N-(3′-aminophenyl)-azacrown. Transmission electron microscopy shows that these amphphiles can form the vesicles with diameters of 30-150 nm and their widths are 5-25 nm when dispersed in water. UV-Vis spectroscopy and differential scanning calorimetry were applied to examine the aggregate state and phase transition behavior of aqueous dipersions of these amphiphiles.
