Abstract. The intramolecular charge separation from the second singlet excited state of Zn-porphyrin derivatives and subsequent charge recombination into the first singlet excited state have been explored. In the framework of the model considered the influence of the medium reorganization energy and dynamic properties of the solvent on the yield of products are investigated. Simulations of the chargeseparated state population dynamics allow reproducing the experimentally observed features of the kinetics in Zn-porphyrin derivatives.

Key words: second excited state, photoinduced electron transfer, nonthermal transitions, solvent relaxation, molecular switch.
