Abstract

Ultrafast photoexcitation dynamics of the bodipy-anthracene-radical triad of the photoexcited quartet state and its control compounds were investigated by fs-laser spectroscopy. The fs-spectroscopy successfully unveiled complicated dynamical processes consisting of electron-transfer, energy-transfer, and charge separated ion-pair generation. Based on the results, a pathway leading to the high-spin state generation is discussed.
