用纳秒时间分辨全内反射荧光法研究了水/1，2-二氯乙烷(DCE)界面上1-PSA的荧光光谱及其动力学。在全内反射条件下观察到了PSA在水/DCE界面的荧光和在水相中的荧光，并根据荧光动力学分析从观察到的光谱中分离了PSA在界面的荧光特征。根据PSA在界面上的吸附和二聚体的形成对结果进行了讨论。
The fluorescence spectra and relevant dynamics of 1-pyrene sulfonate anion (PSA) at a water/1, 2-dichloroethane (DCE) interface were studied by nanosecond time-resolved total internal reflection fluorometry. Both the fluorescence of PSA at a water/DCE interface and that in the water phase were observed under total internal-reflection conditions; also, the fluorescence characteristics at the interface could be separated from the observed spectrum on the basis of analyses of the fluorescence dynamics. The results are discussed in terms of the adsorption and dimer formation of PSA at the interface.
