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 H 2 O. 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.
