摘要：

Diffusionless electron transfer systems, comprised of excited xanthene dyes dissolved in nonpolar or weakly polar electron donor or acceptor, are distinguished by their direct access to the rate constant of electron transfer and by their potentiality for ultrafast electron transfer. We observed short fluorescence lifetimes of less-than-or-equal-to 6 ps for rhodamine 6G dissolved in p-benzoquinone, aniline and N,N-dimethylaniline.
