Abstract

A novel low-molecular-mass gelator containing a redox-active ferrocenyl group, cholesteryl glycinate ferrocenoylamide (CGF), was intentionally designed and prepared. It was demonstrated that the gelator gels 13 out of the 45 solvents tested. Scanning electron microscopy (SEM) measurements revealed that the gelator self-assembled into different supramolecular network structures in different gels. Chemical oxidation of the ferrocenyl residue resulted in phase transition of the gel from gel state to solution state. FTIR and (1)H NMR spectroscopy studies revealed that hydrogen bonding between the gelator molecules in the gel was one of the main driving forces for the formation of the gels.

摘要

一种含有氧化还原活性二茂铁基的新型低分子量凝胶因子，即胆固醇甘氨酸二茂铁酰胺（CGF），被特意设计并制备出来。结果表明，该凝胶因子能使45种测试溶剂中的13种形成凝胶。扫描电子显微镜（SEM）测量显示，该凝胶因子在不同的凝胶中自组装成不同的超分子网络结构。二茂铁残基的化学氧化导致凝胶从凝胶态转变为溶液态。傅里叶变换红外光谱（FTIR）和核磁共振氢谱（¹H NMR）研究表明，凝胶中凝胶因子分子之间的氢键是形成凝胶的主要驱动力之一。
