| الوصف: | In the series of complexes [(4,4'-(X) 2 -2,2'-bpy)(CO) 3 Re I (4,4'-bpy)Re I (CO) 3 (4,4'-(Y) 2 -2,2'-bpy)] 2+ (X, Y=H, CH 3 , NH 2 , CO 2 Et), the ultimate site of the excited electron following metal-to-ligand charge-transfer (MLCT) excitation has been studied by transient absorbance and emission spectroscopies in polar organic solvents. The electron-donating groups NH 2 and Me increase the energy of the π* levels of the 2,2'-bpy ligand. They lead to localization of the excited electron on the bridging 4,4'-bpy ligand, as shown by the appearance of an absorption feature in CH 3 CN in transient absorbance difference spectra |
