Abstract
Light-induced enhancement of the third-order nonlinear optical suscept ibility of a heterodimer consisting of two different porphyrin monomer s, a zinctetra(4-sulfonatophenyl)porphyrin and a zinctetra(4-N-methyl- pyridyl)porphyrin, was observed when the sample was optically pumped b y a 30 ps, 532 nm pump pulse. The temporal behavior of the enhancement was studied. It was found that the enhancement was due predominantly to the population of the charge-separated state with a large electroni c third-order nonlinear optical susceptibility.
