摘　　要：设计合成了双胆固醇取代Schiff碱衍生物,发现该化合物能在苯、CCl4、乙酸丁酯和DMF中自组装形成透明的有机凝胶.扫描电镜和透射电镜照片表明,大量一维凝胶纤维的交叉缠绕构成了三维网络结构.UV-vis吸收光谱表明,在凝胶相中Schiff碱基团之间通过π-π相互作用形成了H-聚集体.A new salicylidene derivative with cholesterol moieties was designed and synthesized. It was found that it could self-assemble into transparent organogels in benzene, CCl4, butyl acetate and DMF. The TEM and SEM images reveal that lots of nanofibers cross-linked into 3D networks, which could prevent the flow of the solvents. The UV-vis absorption spectra illustrate that salicylidene units self-assembled into H-aggregation via π-π interaction.
