Parameters influencing the photo-induced electron transfer from tryptophan-containing peptides to a Ru(II) complex: a systematic study.

Ruthenium(II) polyazaaromatic complexes have gained interest in recent decades as biomolecular tools, especially in the development of new phototherapeutic agents. These light emissive Ru complexes based on π-deficient ligands were first designed to allow a photo-induced electron transfer (PET) with the guanine base in DNA since their (3)MLCT state is… (More)
