or
the like below.
##STR1##
(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.
