摘要：

Fast electron transfer is observed for tetraphenylporphyrin dimers and monomers substituted with the electron acceptor quinone. The transfer rate for the monomer as compared to the dimer is faster by about a factor of 2, which is due to competition between energy transfer among the porphyrin subunits and charge separation. © 1990.
