Photoinduced Intramolecular Tryptophan Oxidation and Excited-State Behavior of [Re(L-AA)(CO)3(r-diimine)] ? (L = Pyridine or Imidazole, AA = Tryptophan, Tyrosine, Phenylalanine)
Original language description
ReI carbonyl-diimine complexes [Re(L-AA)(CO)3(N,N)]+ (N,N = bpy, phen) containing an aromatic amino acid (AA), phenylalanine (Phe), tyrosine (Tyr), or tryptophan (Trp), linked to Re by a pyridine-amido or imidazole-amido ligand L have been synthesized and their excited-state properties investigated by nanosecond time-resolved IR (TRIR) and emission spectroscopy. Near-UV optical excitation populates a ReI(CO)3N,N 3MLCT excited state *[ReII(L-AA)(CO)3(N,N?)]+. Decay to the ground state (50?300 ns lifetime) is the only excited-state deactivation process observed in the case of Phe and Tyr complexes, whereas the Trp-containing species undergo a Trp(indole)*ReII electron transfer (ET) producing a charge-separated (CS) state, [ReI(L-Trp+)(CO)3(N,N?)]+. The ET occurs with a 8?40 ns lifetime depending on L, N,N, and the solvent.
