Patent ID: 7049470

Claim:
A bis(aminostyryl)anthracene compound represented by formula [I], [II], [III], or [IV] where R 2 and R 3 each denotes an unsubstituted aryl group, and R 1 and R 4 each denotes an aryl group represented by formula (1) where R 7 , R 8 , R 9 , R 10 , and R 11 are identical or different groups, at least one of them being a saturated or unsaturated hydrocarbon oxy group or hydrocarbon group having at least one carbon; and R 5 and R 6 are identical or different groups, at least one of them being a hydrogen atom, cyano group, nitro group, or halogen atom where R 12 , R 13 , R 14 , and R 15 are identical or different groups, each denoting an aryl group represented by formula (2) where R 18 , R 19 , R 20 , R 21 , and R 22 are identical or different groups, at least one of them being a saturated or unsaturated hydrocarbon oxy group or hydrocarbon group having at least one carbon; and R 16 and R 17 are identical or different groups, at least one of them being a hydrogen atom, cyano group, nitro group, or halogen atom where at least one of R 23 , R 24 , R 25 , and R 26 denotes an aryl group represented by formula (3), with the remainder being an unsubstituted aryl group where R 29 , R 30 , R 31 , R 32 , and R 33 are identical or different groups, at least one of them being a saturated or unsaturated hydrocarbon amino group; and R 27 and R 28 are identical or different groups, at least one of them being a hydrogen atom, cyano group, nitro group, or halogen atom.
