Bis(aminostyryl)naphthalene compound, synthesis intermediate thereof, and process for production thereof |
摘要 |
A bis(aminostyryl)naphthalene compound represented by the general formula [I] or the like below. (where R<2 >and R<3 >each denotes an unsubstituted aryl group; R<1 >and R<4 >each denotes an aryl group having a specific substituent such as methoxy group; and R<5 >and R<6 >each denotes a cyano group or the like.) A process for producing a bis(aminostyryl)naphthalene 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)naphthalene compound emits intense yellow or red light. The process permits efficient production of the bis(aminostyryl)naphthalene compound.
