PURPOSE:To obtain a light-responsive electrode which is highly responsive to visible light by making a macromolecular complex of the tris (polypyridyl) metal (II) type to be held on the surface of the electrode. CONSTITUTION:A macromolecular complex of the tris (polypyridyl) metal (II) type which is highly responsive to visible light in solution, is held on the surface of an electrode. The macromolecular complex can be synthesized by allowing a macromolecular compound containing a polypyridyl group to react with a cis-bis (polypyridyl) metal (II) complex. In addition to the macromolecular complex, an electron-accepting redox agent such as a viologen or an electron-repelling redox agent such as an aromatic amine is held on the surface of the electrode so as to increase the photoelectric current of the electrode. When visible light is irradiated upon a light-activated electrode (working electrode) after the active electrode and a counter electrode which is connected to the active electrode are immersed in a solvent, a photoelectric current is observed. |
