UV spectra of the n -octanol gels formed by the three gelators indicate that the K bands of benzene rings are red shifted. It reveals that the π-π stack is one of the driving forces for the self-assembly of the gelators. The extent of red shifts of K bands depends on the amount of methyl groups in benzene rings which is in accord with the stabilities of the gels formed by such three gelators.
紫外吸收光谱表明,对比其溶液态,三种衍生物聚集体苯环的K带发生红移,表明π-π堆积作用是亚苄基山梨醇衍生物凝胶剂自组装的驱动力之一;红移的幅度随苯环上甲基数量的增加而增加,这与三种衍生物形成的分子凝胶的热稳定性相吻合。
