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.

An eco-friendly synthesis of Au–Ag@AgCl NCs was described using the tuber extract of Nephrolepis cordifolia. The synthetic utility of the NCs was demonstrated by the synthesis of pharmaceutically important quinoline derivatives.

Gold-catalyzed synthesis of quinoline derivatives via [4 + 2] annulation between terminal arylynes and nitrones is described. Our mechanistic analysis supports the participation of alkynylgold intermediates, instead of a typical gold–carbene species in recently reported gold catalysis. These nucleophilic alkynylgold species react with nitrones via Povarov-type reactions. Cheap, readily available materials
