Abstract

The rate of electron transfer from the lowest excited singlet state of a porphyrin to an acceptor was measured in 2-MTHF glass at 77 K for a series of molecules. Analysis of the rate data as a function of free energy of reaction reveals that the ion-pair state of the oxidized donor and reduced acceptor is destabilized in solid solution by about 0.7 eV relative to its energy in polar liquids.
