AMINOSTYRYLANTHRACENE COMPOUND, SYNTHETIC INTERMEDIATE THEREOF, AND PROCESS FOR PRODUCTION THEREOF

摘要

This invention is an aminostyrylanthracene compound represented by, for example, the following general formula [I]. This compound is produced by condensation from a corresponding aminobenzaldehyde and a phosphonic ester or phosphonium salt. [where, in the general formula [I] above, R2 represents an unsubstituted aryl group, R1 represents an aryl group which may have a variety of substituents, and R3 to R5 each represent a hydrogen atom, a cyano group, or a hydrocarbon group.]
