摘　　要：本文将四唑基团引入偶氮苯衍生物制备了化合物3,利用十八胺(OA)与其复合构筑了一种基于氢键等多重协同非公价键作用的的二组分相选择性超分子凝油剂3-OA,并通过~1H NMR、ESI-TOF MS、FT-IR及流变学对其结构和凝胶性质进行了研究。另外,实验结果表明,该超分子凝胶对光、热及振荡等外部刺激具有良好的可逆响应性,同时该胶凝剂能够选择性的从油(有机溶剂)-水混合物中胶凝多种有机溶剂和油品,如甲苯、原油、食用油等,且其成胶性能不受共存的无机盐的影响。A novel type of two-component supramolecular oil gelling agent,3-OA,was constructed based on non-covalent interactions using tetrazolyl derivative 3 with octadecylamine（ OA） and fully characterized using a number of structural and spectral techniques.The self-assembled 3-OA gels displayed remarkable stimuli-responsiveness.In addition,it was found that 3-OA could selectively immobilize several kinds of aromatic organic solvents and oils,and its gelling abilities were barely affected by the co-existed inorganic salts.
