Studies of photon-induced electron excitation and transfer

Studies of photon-induced electron excitation and transfer in organic small molecule-based materials for applications in luminescence sensing, solar cells, and photodynamic therapy

Three projects are related to this topic. The first focuses on studying the mechanism of electron excitation and transfer upon photon absorption in fluorescence sensors. The second examines the mechanism of electron excitation and transfer in organic dyes used for solar cells. The third investigate the mechanism and kinetics of generating long-lived triplet states in photodynamic therapy photosensitizers.
