  摘要：

  Photochemical and photophysical studies are reported for the complex, fac-(bpy)Re-I(CO)(3)(DA)(1+) (e-1), where bpy is 2,2'-bipyridine and DA is a ''reactive donor ligand'' that contains a vicinal diamine functionality. Photoexcitation of e-l into the dst (Re) --> pi* (bpy) metal-to-ligand charge transfer (MLCT) excited state leads to formation of the ligand-to-ligand charge transfer (LLCT) state, *(bpy(.-))Re-I(CO)(3)(DA(.+))(1+), via diamine ligand-to-Re electron transfer. In the LLCT state, the reactive donor ligand radical cation undergoes an exceedingly rapid heterolytic C-C bond fragmentation reaction to produce an iminium ion and an cr-amino radical fragment. Steady-state photochemical studies reveal that in air-saturated solution the only products observed arise from C-C bond fragmentation, which implies that under these conditions bond fragmentation is irreversible. Laser flash photolysis studies indicate that the a-amino radical that is produced by bond fragmentation in the LLCT state absorbs strongly in the near-UV region. A kinetic analysis is carried out under the assumptions that: (1) the quantum yield for formation the LLCT state can be derived from MLCT emission lifetime data on the diamine complex and a suitable non-donor-substituted model complex and (2) C-C bond fragmentation is irreversible. This analysis affords lower limits for the rates of back electron transfer and bond fragmentation (1.5 x 10(8) and 1.0 x 10(8) s(-1), respectively).
