摘要

通过微调芳香链长度与环键型,利用胺醛缩合反应,合成了6种基于动态共价键的胆固醇基凝胶因子。凝胶因子分子结构包含非共价键环且刚性链越长时,其凝胶能力、热稳定性越好。扫描电子显微镜分析显示凝胶因子形成凝胶的超分子结构主要为典型的三维网络状结构。傅里叶变换红外光谱分析表明氢键作用是超分子凝胶形成的主要驱动力。紫外-可见分光光度法分析表明目标凝胶因子在环己烷中形成凝胶可吸附有机染料甲基橙和亚甲基蓝,吸附率可达80.2%和82.6%。

Abstract

By subtly adjusting the length of aromatic chains and the type of ring bonds,six cholesterol-based gelators with dynamic covalent bonds were synthesized through amine-aldehyde condensation reactions.The gelator molecules,which contained non-covalent bond rings and longer rigid chains,exhibited good gelation abilities and thermal stability.Scanning electron microscopy (SEM) showed that the supramolecular structures of the gels formed by gelators were mainly typical three-dimensional network structures.Fourier transform infrared (FT-IR) suggested that hydrogen bonding were the main driving forces for the formation of the supramolecular gels.Ultraviolet-visible (UV-Vis) indicated that the target gelators formed gels in cyclohexane and could effectively adsorb organic dyes like methyl orange and methylene blue.The adsorption rates were 80.2% and 82.6%,respectively.
