Abstract: Photoinduced electron transfer reaction of anthracene with phenothiazine(PTZ)occurs in the membrane phase of the SDS (sodium dodecyl sulfate)/benzyl alcohol/H2O microemulsion. PTZ exists in the membrane phase because the rate for the photoinduced reaction between CHCl3 and PTZ in microemulsion is much slower than that in BA. Anthracene locates in the membrane phase or the oil core of the O/W microemulsion and in the oil continuous phase of the W/O microemulsion. The quenching of the excited anthracene by PTZ occurs in the membrane phase either for the W/O microemulsion or for the O/W microemulsion.
