| Research Abstract |
Pyrazine-bridged dinuclear ruthenium complexes show color change in solution by selective dissociation of the bridging ligand under visible-light irradiation. The dinuclear complexes display photochromic behavior, since they are recovered by heating. In this study, we synthesized the dinuclear complexes having redox responsive switchingmoieties, such as benzoquinone and hydroquinone, and the photodissociation rates of these complexes have been measured. It was found that the photodissociation rate of thedinuclear complexes having benzoquinone moieties was depressed. The observation suggests that the application of the complexes developed in this study to the new photochromic material which is controllable by external factor would be possible.
