Abstract:
A bis(aminostyryl)benzene compound of the following formula [I], [II], [III] or [IV]: wherein R2 and R3 independently represent an unsubstituted aryl group, and R1 and R4 independently represent an aryl group represented by the following formula (1) in which R9, R10, R11, R12 and R13 may be the same or different and at least one thereof is a member selected from an alkoxy group having from 1 to 4 carbon atoms, which may be saturated or may have a double bond, a cyclohexyloxy group, a phenoxy group, an alkyl or alkenyl group having from 1 to 4 carbon atoms, a cyclohexyl group, and a phenyl group, and the others represent a hydrogen atom, and R5, R6, R7 and R8 may be the same or different and at least one thereof represents a member selected from a cyano group and a nitro group, and the others independently represent a hydrogen atom, a cyano group, a nitro group or a halogen atom; wherein R14, R15, R16 and R17 may be the same or different and independently represent an aryl group of the following formula (2) in which R22, R23, R24, R25 and R26 may be the same or different, and at least one thereof is a member selected from an alkoxy group having from 1 to 4 carbon atoms, which may be saturated or may have a double bond, a cyclohexyloxy group, a phenoxy group, an alkyl or alkenyl group having from 1 to 4 carbon atoms, a cyclohexyl group, and a phenyl group, and the others represent a hydrogen atom, and R18, R19, R20 and R21 may be the same or different and at least one thereof represents a member selected from a cyano group and a nitro group, and the others independently represent a hydrogen atom, a cyano group, a nitro group or a halogen atom; wherein at least one of R27, R28, R29 and R30 represents an aryl group of the following formula (3) and the others independently represent an unsubstituted aryl group in which R35, R36, R37, R38 and R39 may be the same or different and at least one thereof is a group selected from a dialkylamino or dialkenylamino group whose alkyl or alkenyl moiety has from 1 to 4 carbon atoms, a dicyclohexylamino group, and a diphenylamino group, and the others represent a hydrogen atom, and R31, R32, R33 and R34 may be same or different and at least one thereof represents a group selected from a cyano group and a nitro group, and the others independently represent a hydrogen atom, a cyano group, a nitro group or a halogen atom; or wherein R41 and R42 may be the same or different and independently represent an aryl group of the following formula (4) in which R48, R49, R50, R51 and R52 may be the same or different and independently represent a hydrogen atom provided that at least one thereof is a member selected from an alkoxy group having from 1 to 4 carbon atoms, which may be saturated or may have a double bond, a cyclohexyloxy group, a phenoxy group, an alkyl or alkenyl group having from 1 to 4 carbon atoms, a cyclohexyl group, and a phenyl group, and the others represent a hydrogen atom, and R40 and R43 may be the same or different and independently represent an aryl group of the following in which R53, R54, R55, R56, R57, R58 and R59 may be the same or different and independently represent a hydrogen atom, or at least one thereof is a member selected from an alkoxy group having from 1 to 4 carbon atoms, which may be saturated or may have a double bond, a cyclohexyloxy group, a phenoxy group, an alkyl or alkenyl group having from 1 to 4 carbon atoms, a cyclohexyl group, and a phenyl group, and the others represent a hydrogen atom, and R44, R45, R46 and R47 may be the same or different and at least one thereof represents a member selected from a cyano group and a nitro group, and the others independently represent a hydrogen atom, a cyano group, a nitro group or a halogen atom.
