実験手順

As shown in scheme 3, 3,6-dibromo-9-hexyl-9H-carbazole (31) is reacted with 1-methyl-2-(tributylstannyl)-1H-pyrrole by Stille coupling reaction to obtain N-methyl-2-(3-bromo-9-hexyl-9H-carbazol-6-yl)pyrrole (32). Then, in the presence of sodium tert-butoxide, Pd(dba)2, and tri-tert-butyl phosphine, N-methyl-2-(3-bromo-9-hexyl-9H-carbazol-6-yl)pyrrole (32) is reacted with diphenylamine to obtain N-methyl-2-(3-diphenylamino-9-hexyl-9H-carbazol-6-yl)pyrrole (33). n-butyl lithium is reacted with N-methyl-2-(3-diphenylamino-9-hexyl-9H-carbazol-6-yl)pyrrole (33), and then tributylstannylchloride is added thereto to obtain N-methyl-2-(3-diphenylamino-9-hexyl-9H-carbazol-6-yl)-5-tributyl-stannylpyrrole (34). N-methyl-2-(3-diphenylamino-9-hexyl-9H-carbazol-6-yl)-5-tributylstannylpyrrole (34) is reacted with 5-bromo-2-thiophene-carboxaldehyde by Stille coupling reaction to obtain 5-[N-methyl-2-(3-diphenylamino-9-hexyl-9H-carbazol-6-yl)pyrrol-5-yl]thiophene-2-carbaldehyde (35). Finally, 5-[N-methyl-2-(3-diphenylamino-9-hexyl-9y-carbazol-6-yl)pyrrol-5-yl]thiophene-2-carbaldehyde (35) is reacted with cyanoacetic acid in acetic acid by using ammonium acetate as a catalyst, and (E)-2-cyano-3-[5-(N-methyl-2-(3-diphenylamino-9-hexyl-9H-carbazol-6-yl)pyrrol-5-yl)thiophen-2-yl]acrylic acid (36) is obtained.
