Abstract

Abstract: A series of donor-accepter systems linked by bisphenol A were synthesized in this paper.The electron donor is 9,10-dimethoxyanthracene.The dependence of photo induced electron transfer rates on the exothermicity of the reaction was studied.The rate constantsof photo induced electron transfer in these systems first increase with decreasing free energychange up to A △G value of-1 eV,thereafter the rate constants of electron transfer remainalmost unchanged as the value of △G decreases.The result is in consistent with Rehm-Weller relationship.

Key words: electron transfer, anthracence, bisphenol A To whom correspondence should be addressed.
