Under an atmosphere of argon, 9-bromo-10-(4-(2-phenylvinyl)-phenyl)anthracene (3.1 g, 7.1 mmole), 4-(2,2-diphenylvinyl)phenylboronic acid (2.4 g, 8.0 mmole, 1.1 eq) and tetrakis(triphenylphosphine)-palladium(0) (0.16 g, 0.14 mmole, 2% Pd) were suspended into toluene (25 ml). To the obtained suspension, a 2 M aqueous solution of sodium carbonate (2.5 g, 24 mmole, 3 eq/12 ml) was added and the resultant mixture was heated under refluxing for 10 hours. The reaction mixture was filtered and washed with water and methanol and a yellow solid was obtained. The obtained solid was suspended in boiling toluene (50 ml), cooled while being left standing, filtered and washed with toluene and a light yellow solid (3.8 g, 88%) was obtained.
