1. A diamine compound represented by the following general formula (1):wherein
each * represents an asymmetric carbon atom, R1 represents a group selected from alkyl groups having 1 to 10 carbon atoms, halogenated alkyl groups having 1 to 10 carbon atoms, and aryl groups having 6 to 30 carbon atoms, the aryl groups optionally having one or more substituents selected from alkyl groups having 1 to 10 carbon atoms, halogenated alkyl groups having 1 to 10 carbon atoms, and halogen atoms, R2 and R3 each independently represent a group selected from alkyl groups having 1 to 10 carbon atoms, phenyl groups, and cycloalkyl groups having 3 to 8 carbon atoms, the phenyl groups optionally having one or more substituents selected from alkyl groups having 1 to 10 carbon atoms, alkoxy groups having 1 to 10 carbon atoms, and halogen atoms, and each hydrogen atom of the cycloalkyl groups being optionally replaced by an alkyl group having 1 to 10 carbon atoms, or R2 and R3 form a ring together with carbon atoms to which R2 and R3 are bonded, Y represents an alkylene group selected from optionally branched alkylene groups having 1 to 10 carbon atoms, and alkylene groups containing a benzene ring as a skeleton, the benzene ring optionally having one or more substituents selected from alkyl groups having 1 to 10 carbon atoms, alkoxy groups having 1 to 10 carbon atoms, and halogen atoms, X represents a Brønsted acid selected from a boric acid group (—B(OH)2), a carboxyl group (—COOH), a phosphoric acid group (—P(═O)(OH)2), and phosphoric acid monoester groups (—P(═O)(OH)(OR21), where R21 represents an alkyl group having 1 to 5 carbon atoms, and Z represents a hydrogen atom or a deuterium atom. |
