Intramolecular charge separation in a hydrogen bonded tyrosine–ruthenium(<scp>ii</scp>)–naphthalene diimide triad

Abstract

Long-lived charge-separated states in the ns to [micro sign]s range were observed upon laser flash excitation of a donor-chromophore-acceptor triad based on tris(bipyridine) ruthenium(ii) as photo-sensitizer, naphthalene diimide as acceptor, and a hydrogen bonded phenol as donor.
