摘　　要：设计合成了四苯乙烯衍生物凝胶因子(TP),该凝胶因子可以在1,4-二氧六环中形成有机凝胶.通过紫外可见光谱、荧光光谱、红外光谱、扫描电镜、X-射线粉末衍射和接触角等技术对该凝胶因子的自组装过程进行了详细表征.结果表明:该凝胶体系具有明显的聚集诱导发光的性质,凝胶因子TP在自组装过程形成了且具有一定的疏水性,其接触角为136°.氢键作用和范德华力可能是该自组装体系的主要驱动力.A new gelator TP based on tetraphenylethylene derivative was designed and synthesized which could form an organogel in 1,4-dioxane.The self-assembly process of TP was characterized by UV-Vis absorption spectroscopy,fluorescence emission spectra,Fourier transform infrared spectroscopy,scanning electron microscopy and water contact angle.The experiment results showed that a fibers structure obtained in the self-assembly process had some hydrophobility with the contact angle of 136°.The hydrogen bond and van der Waals force were the main driving force for the gel formation.
