摘　　要：Photoinduced electron-transfer system of anthracene-N, N-diethylaniline (MA) was studied in the oil in water (O/W) microemulsions formed by SDS (sodium dodecyl sulfate), BA (benzyl alcohol) and H2O. The time-resolved fluorescence study showed mat the fluorescence quenching of the excited anthracene by DEA occurs at the interface of the O/W microemulsions. Besides as the quencher of the excited anthracene, N, N-diethylaniline could act as a cosurfactant to change the structures of the microemulsions, Just as BA did. The quenching rate constants for the different structures of the system were determined.Photoinduced electron-transfer system of anthracene-N, N-diethylaniline (MA) was studied in the oil in water (O/W) microemulsions formed by SDS (sodium dodecyl sulfate), BA (benzyl alcohol) and H2O.
