Abstract:
A compound represented by formula (1) or formula (11). X-A1-(N=N-A2)n-N=N-A3-Y … (1) (In formula (1), -A1- and -A2- each independently represent a divalent group of an optionally substituted aromatic heterocycle including one or more S atoms in which atoms other than carbon atoms constituting the aromatic heterocycle are not adjacent, a divalent group of an optionally substituted benzoisothiazole ring, or a divalent group of an optionally substituted aromatic hydrocarbon ring, -A3- represents a divalent group of an optionally substituted aromatic hydrocarbon ring, -X represents a branched C3 or higher alkyl group, alkoxy group, or alkylsulfanyl group, -Y represents a monovalent organic group, and n represents 1, 2, or 3. When n is 2 or 3, the multiple -A2- may be the same or different. However, -A1- and -A2- are not both divalent groups of an optionally substituted aromatic hydrocarbon ring.) X-A41-(N=N-A42)n-N=N-A43-Y … (11) (In formula (11), at least one -A42- is a divalent group of an optionally substituted aromatic heterocycle including one or more S atoms, -A41- and -A43- each independently represent a divalent group of an optionally substituted aromatic hydrocarbon ring, X represents a branched C3 or higher alkyl group, alkoxy group, or alkylsulfanyl group, -Y represents a monovalent organic group, and n represents 1, 2, or 3. When n is 2 or 3, the multiple -A42 may be the same or different.)
