## Abstract **π–π assisted**: Photoinduced electron transfer from cofacial porphyrin dimers to electron acceptors is prominently accelerated, whereas the back electron transfer is decelerated, relative to the corresponding porphyrin monomer (see figure).magnified image The radical cation of zinc t
The triplet-triplet annihilation of the lowest-lying excited states of porphyrins and phthalocyanines has been investigated by laser flash photolysis. Spectroscopic and kinetic evtdence indicates that the lowest-lying triplet dimerizes into excimers at a rate less than diffusion controlled.
