Photochemistry of P,N-bidentate rhenium(<scp>i</scp>) tricarbonyl complexes: reactive species generation and potential application for antibacterial photodynamic therapy

Abstract

in irradiated solutions of the compounds, which follows the same tendency as their singlet oxygen generation quantum yield: RePNBr > RePNTfO > RePNNBr, while no antibacterial activity is observed in the darkness. This result indicates that the generation of singlet oxygen plays a key role in the antibacterial capacity of these complexes.
