摘要：

Photoinduced electron transfer (PET) from N,N-dimethylaniline (DMA) to oxazine 1 (OX-1) is studied in micelles. It is observed that in anionic (sodium dodecyl sulfate, SDS) and neutral (Triton X-100, TX) micelles the rate of electron transfer (ET) from DMA to OX-1 is respectively 6.5 and 3 times smaller than that in water, and respectively 162 and 90 times smaller than that in neat DMA. The lower ET quenching constant in micellar media is ascribed to the greater donor-acceptor distance in the micelles. (C) 1999 Elsevier Science B.V. All rights reserved.
