Oxidation process and reduction method using a manufacturing method quinolinium ion derivatives, of quinolinium ion derivatives, products using the quinolinium ion derivative, the quinolinium ion derivatives

摘要

Providing an electron donor-acceptor linked molecules obtained charge-separated state which not only a high oxidizing power and long lifetime also has a high reducing power. Quinolinium ion derivative represented by the following formula (I), a compound of the present invention, a salt thereof or a tautomer or stereoisomer thereof. [Formula 1] The formula (I), R ¹ denotes a hydrogen atom, an alkyl group, Ar ¹ ~Ar ³ is an electron-donating group or a hydrogen atom. By having the above structure, charge-separated state which not only a high oxidizing power and long lifetime also has a high reducing power is obtained, and the photocatalyst, light sensitizers, dyes, oxidizing agents, the compounds of the present invention, the reducing agent , it can be used for various products dye-sensitized solar cell, an organic EL element.
