内容記述
We investigated the excited state of a ring-shaped dinuclear Re(I) diimine bis-carbonyl complex that shows promise with regard to efficient photosensitized reactions and multi-electron storage, using time-resolved IR (TR-IR) vibrational spectroscopy and quantum chem. calcns. Anomalous peaks in the CO stretching region of the TR-IR spectrum were well reproduced by the calcns. It was found that metal-to-ligand charge transfer occurs only in one of the Re complex units, and that the excited state geometry is deformed relative to the ground state in order to relax the assocd. steric tension. This structural deformation generates the unique photophys. properties of the complex. [on SciFinder(R)]
