Abstract
Donor-acceptor systems where the rate of radiationless electronic ener gy transfer is influenced by the electronic structure of the interveni ng medium are studied. In this paper we report the observation of medi ated energy transfer in a series of geometrically well-defined porphyr in dimers. The dimers consist of a free base porphyrin (5,15-diphenyl- alpha,beta-octaalkylporphyrin, H2P) and the corresponding zinc porphyr in (ZnP) as acceptor and donor, respectively, connected by aryl chromo phores with varying energies of the lowest excited states.
