Abstract:
1. An indolium compound represented by general formula (IV): wherein: ring A represents a benzene or naphthalene ring; Z represents an alkyl group having 1 to 8 carbon atoms which optionally may be substituted with a halogen atom or optionally may be interrupted by —O—, —CO—, —OCO—, or —COO—, a sulfonyl group having a hydrocarbyl group having 1 to 8 carbon atoms, a sulfinyl group having a hydrocarbyl group having 1 to 8 carbon atoms, an alkylamino group having an alkyl group having 1 to 8 carbon atoms, a dialkylamno group having alkyl groups having 1 to 8 carbon atoms, a cyano group, a nitro group, a hydroxyl group, or a halogen group; R R R Y represents a group represented by general formula (III); wherein, in general formula (II): the bond between S and T is a double bond or a triple bond; S represents a carbon atom; T represents a carbon, oxygen, or nitrogen atom; x, y, and z represent 0 or 1; R R R wherein, in general formula (II′): the bond between S′ and T′ is a double bond; S′ represents a carbon atom; T′ represents a carbon, oxygen, or nitrogen atom; the ring containing S′ and T′ represents a 5-membered ring which optionally may contain a hetero atom or a 6-membered ring which optionally may contain a hetero atom, or a naphthalene, quinoline, isoquinoline, anthracene, or anthraquinone ring, and said rings containing S′ and T′ may optionally be substituted with a halogen atom, or a nitro, cyano, alkyl, or alkoxy group, wherein, in formula (III): R Q represents a direct bond or an alkylene group having 1 to 8 carbon atoms which optionally may be substituted, where a methylene group of the alkylene group having 1 to 8 carbon atoms optionally may be replaced by —O—, —S—, —CO—, —COO—, —OCO—, —SO M represents Fe, Co, Ni, Ti, Cu, Zn, Zr, Cr, Mo, Os, Mn, Ru, Sn, Pd, Rh, Pt, or Ir; R X, as a substituent, represents an alkyl group having 1 to 8 carbon atoms which optionally may contain a halogen atom or a hydroxy group or optionally may be interrupted by an ether bond or as a substituent, an alkoxy group having 1 to 8 carbon atoms which optionally may contain a halogen atom or a hydroxy group or optionally may be interrupted by an ether bond, or a hydroxy, nitro, cyano, or halogen group; n represents an integer from 0 to 4; q represents an integer from 0 to 4; An p represents a coefficient to keep a neutral charge.
