A bis(aminostyryl)naphthalene compound representednby the general formula [I] or the like below.n n(where R 2 and R 3 each denotes an unsubstituted aryl group;nR 1 and R 4 each denotes an aryl group having a specificnsubstituent such as methoxy group; and R 5 and R 6 eachndenotes a cyano group or the like.) n A process for producing anbis(aminostyryl)naphthalene compound represented by thengeneral formula [I] by condensation of, for example, 4-(N,N-diarylamino)benzaldehydenwith diphosphonic ester orndiphosphonium. n The bis(aminostyryl)naphthalene compound emitsnintense yellow or red light. The process permitsnefficient production of the bis(aminostyryl)naphthalenencompound. |
