Bis (aminostyryl) anthracene compound, synthesis is intermediate thereof, and process for production thereof

摘要

A bis(aminostyryl)anthracene compound represented by the general formula [I] or the like below. (where R² and R³ each denotes an unsubstituted aryl group; R¹ and R⁴ each denotes an aryl group having a specific substituent such as methoxy group; and R⁵ and R⁶ each denotes a cyano group or the like.) A process for producing a bis(aminostyryl)anthracene compound represented by the general formula [I] by condensation of, for example, 4-(N,N-diarylamino)benzaldehyde with diphosphonic ester or diphosphonium. The bis(aminostyryl)anthracene compound emits intense yellow or red light. The process permits efficient production of the bis(aminostyryl)anthracene compound.
