摘要：

The emission properties, electrochemical potentials, and picosecond transient absorption spectra of the chromophore-quencher complex, [(bpy)Re1(CO)3DMABN]+ (where bpy = 2,2′-bipyridine and DMABN = 4-(dimethylamino)benzonitrile) were studied in CH2Cl2, CH3CN, and in mixtures of the two solvents. Strong dπ(Re) → π*(bpy) MLCT emission is observed in CH2Cl2, but not in CH3CN. The MLCT quenching process is attributed to the presence of a ligand-to-ligand charge-transfer state in the excited-state manifold. © 1990 American Chemical Society.
