摘要:

合成了一种以邻羧基苯甲酰二茂铁为疏水链聚乙二醇单甲醚为亲水链的新型rod-coil两亲性金属有机低聚物,并对其在溶液中的自组装行为进行了研究.研究表明,在不同的起始浓度下,该化合物可自组装形成球形、扭曲的蠕虫状胶束和囊泡,二茂铁和苯环间的π-π相互堆叠是形成扭曲型蠕虫状胶束的主要因素.

关键词: 两亲性, 低聚物, rod-coil, 二茂铁, 自组装

Abstract:

A novel amphiphilic rod-coil organometallic oligomer with o-ferrocenylcarbonyl benzoic acid (FcBA) as the hydrophobic short-rod and with methoxy poly (ethylene glycol) (mPEG) as the hydrophilic coil chain has been obtained and the self-assembly behavior of the obtained oligomer was investigated under different initial concentrations. It was found that besides spherical and vesicle assemblies, a new type of morphology, twisty wormlike shape, was formed in the process of self-assembly and the π-π interaction between ferrocene and benzene ring was discussed.

Key words: amphiphilic, oligomer, rod-coil, ferrocene, self-assembly
