Abstract
Apparently solvent-mediated and not throughbond photoinduced electron transfer (ET) takes place from the porphyrin (P) unit to the methylviologen (MV2+) unit in the rigid U-shaped molecules 1 (i.e., k(TS)/(ET) > k(TB)/(ET); TS = through-solvent, TB = through-bond). The ratio of the rates of charge separation to charge recombination is greater than 1400:1.
