| 摘 要： | 胶束微观极性与微观粘度等微环境性质的研究近来已引起人们越来越广泛的注意。已有的研究工作主要限于碳氢表面活性剂体系,全氟表面活性剂体系的研究为数甚少。通常认为全氟表面活性剂有疏油性,因而对于全氟表面活性剂胶束能否加溶碳氢有机物,加溶部位胶束微环境性质如何,各种利用有机探针分子的光物理方法能否用于全氟胶束的物理化学性质的研究等问题很少有研究工作报道。本文研究了全氟辛酸盐胶束加溶芘的特性。实验

| Abstract: | The solubilization of pyrene in perfluorooctoate micelles with addition of N(C_2H_5)_4Br,N(C_4H_9) (C_2H_5)_3Br and N(C_4H_9)_4Br have been studied by steady fluorescence measurements. The results show that the perfluorooctoate micelles can solubilize pyrene, and the maximal amount of pyrene solubilized is increased considerably on the addition of the alkylammonium bromide; the perfluo-micelles quench the fluorescence of pyrene solubilized into it; the solubilizing sites are all near the stern layer of the micelles, and can be changed by the addition of the alkylammonium with different hydrophobicity due to the stronger interaction between pyrene and the hydrocarbon of the ammonium than that between pyrene and fluorocarbon chain of the surfactant. |
