【摘要】 研究了阳离子表面活性剂ＣＴＡＢ在临界胶束浓度（ＣＭＣ） 前对１ － 芘丁酸（ＰＢＡ） 和１ － 萘乙酸（ＮＡＡ） 荧光光谱的影响， 观测到ＰＢＡ和ＮＡＡ激基缔合物的发光． 实验证明： ＣＭＣ前ＣＴＡＢ 能够诱导ＰＢＡ， ＮＡＡ激基缔合物的形成． 这一结果为设计阴离子表面活性剂的荧光检测新方法提供了理论基础．更多还原

【Abstract】 The effect of cationic surfactant CTAB on the fluorescece of 1-pyrenebutyric acid and 1-Naphthylacetic acid was studied below the CMC of CTAB.The excimer emission of PBA and NAA was observed.It was concluded that the cationic surfactant,CTAB at concentration below its CMC could induce the formation of PBA and NAA excimer.This result forms the basis for the sensing assay of anionic surfactant by fluorescence spectroscopy.更多还原
