Abstract

The present invention provides heteropolycyclic compounds represented by General Formulae (1) and (2): wherein R1 is a straight- or branched-chain C1-C10 alkyl group or the like; R2 and R3 are the same or different and are each a straight- or branched-chain C1-C10 alkyl group or the like; R4 and R5 are each a hydrogen atom; X is —OH or the like; X′ is a straight- or branched-chain C1-C10 alkyl group or the like; and Z is —O— or the like. The heteropolycyclic compounds of the present invention have appropriate optical absorption wavelengths and fluorescence wavelengths and a high luminescence intensity, and can be advantageously used in various applications as colorants that have excellent performance in terms of heat resistance, light resistance, solubility, dispersibility in resist materials, solid luminescence, etc.

A heteropolycyclic compound represented by General Formula (1):

wherein R1 is a straight- or branched-chain C1-C10 alkyl group, a substituted or unsubstituted C5-C10 cycloalkyl group or a substituted or unsubstituted phenyl group;
R2 and R3 are the same or different and are each a straight- or branched-chain C1-C10 alkyl group, a substituted or unsubstituted C5-C10 cycloalkyl group or a substituted or unsubstituted phenyl group, or R2 and R3 may be linked to each other to form, together with the nitrogen atom to which they are attached, a heterocyclic ring;
R4 and R5 are each a hydrogen atom;
R2 and R4 and/or R3 and R5 may be linked to each other to form a straight- or branched-chain C2-C7 alkylene group;
X is a hydrogen atom, a straight- or branched-chain C1-C10 alkyl group, a substituted or unsubstituted C5-C10 cycloalkyl group, a substituted or unsubstituted phenyl group, a halogen atom, an —OCOR6 group, an —OR group, an SR6 group or an —NR6R7 group;
R6 and R7 are the same or different and are each a hydrogen atom, a straight- or branched-chain C1-C6 alkyl group or a substituted or unsubstituted C5-C10 cycloalkyl group;
and
Z is a divalent group.
