An electron donor-acceptor dyad is provided that can provide a charge-separated state with longevity and not only high oxidizing power but also high reducing power. A compound of the present invention is a quinolinium ion derivative represented by the following formula (I), a stereoisomer or tautomer thereof, or a salt thereof:
where R
1
is a hydrogen atom or an alkyl group, and Ar
1
to Ar
3
each are a hydrogen atom or an electron-donating group. The compound of the present invention has the above-mentioned structure and therefore can provide a charge-separated state with longevity and not only high oxidizing power but also high reducing power and can be used for various products such as photocatalysts, photosensitizers, dyes, oxidants, reductants, dye-sensitized solar cells, and organic EL devices.
提供了一个电子给体-受体二聚体,可以提供一个具有长寿命的电荷分离状态,不仅具有高氧化能力,而且具有高还原能力。本发明的化合物是由以下式(I)表示的喹啉离子衍生物,其立体异构体或互变异构体,或其盐:
其中R1是氢原子或烷基,Ar1至Ar3分别是氢原子或电子给体基团。本发明的化合物具有上述结构,因此可以提供一个具有长寿命的电荷分离状态,不仅具有高氧化能力,而且具有高还原能力,并且可用于各种产品,如光催化剂、光敏剂、染料、氧化剂、还原剂、染料敏化太阳能电池和有机EL器件。
