실험 절차

As shown in Scheme 3, 7-bromo-9H-fluoren-2-ylamine is reacted with 1-iodobutane to form 7-bromo-9,9-dibutyl-9H-fluoren-2-ylamine (31); and 2-Iodo-9H-fluorene is reacted with 1-iodobutane to form 9,9-dibutyl-2-iodo-9H-fluorene (32). Then, 7-bromo-9,9-dibutyl-9H-fluoren-2-ylamine (31) is reacted with 9,9-dibutyl-2-iodo-9H-fluorene (32) by Ullman coupling reaction to obtain (7-bromo-9,9-dibutyl-9H-fluoren-2-yl)-bis-(9,9-dibutyl-9H-fluoren-2-yl)amine (33). Next, (7-bromo-9,9-dibutyl-9H-fluoren-2-yl)-bis-(9,9-dibutyl-9H-fluoren-2-yl)amine (33) is reacted with 5-formyl-2-thiopheneboronic acid by Suzuki coupling reaction to obtain 5-{7-[bis-(9,9-dibutyl-9H-fluoren-2-yl)amino]-9,9-dibutyl-9H-fluoren-2-yl}-thiophene-2-carbaldehyde (34a). Finally, in acetonitrile, 5-{7-[bis-(9,9-dibutyl-9H-fluoren-2-yl)amino]-9,9-dibutyl-9H-fluoren-2-yl}-thiophene-2-carbaldehyde (34a) is reacted with cyanoacetic acid by using piperidine as a catalyst, to obtain 3-(5-{7-[bis-(9,9-dibutyl-9H-fluoren-2-yl)amino]-9,9-dibutyl-9H-fluoren-2-yl}-thiophen-2-yl)-2-cyano-acrylic acid (35a).
