摘　　要：利用7-羟基香豆素、1,10-二溴癸烷和盐酸二甲胺合成了一种双重刺激响应型的表面活性剂7-(氧-10-二甲氨基-癸基)-香豆素(7-OAC)。通入CO_2或N_2,可实现表面活性的"开"与"关",也可利用其结构中的香豆素基团在300 nm以上紫外光下进行光二聚反应。通过质谱、核磁等表征了其结构,测定了其表面性能及N_2/CO_2和双重光刺激响应性能。A kind of dual stimuli-responsive surfactant 7-OAC has been synthesized using 7-hydroxycoumarin and dimethylamine. The surface activity of the surfactant can be switched ＂on＂by bubbling CO2 and switched ＂off＂by bubbling N2. In addition,this surfactant can be photo-dimerized when exposed to UV lights above 300 nm,due to the coumarin groups. The structure of the product was determined by mass spectra and 1 H NMR. And the performance of the surfactant was determined by measuring the CMC and CO2/ N2 and photo dual stimuli-responsive behaviors.
