Reaction Steps

A mixture of 6.5 g (14 mmol) of 2-(4-(10-bromoanthracen-9-yl)naphthalene-1-yl)thiophene, 7.53 g (16 mmol) of 2-(10,10-dimethyl-10H-indeno[1,2-b]triphenylen-12-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane, 0.16 g (0.14 mmol) of tetrakis(triphenylphosphine)palladium, 11 ml of 2M Na2CO3, 30 ml of EtOH and 65 ml toluene was degassed and placed under nitrogen, and then heated at 90° C. for 4 h. After finishing the reaction, the mixture was allowed to cool to room temperature. Than 500 ml MeOH was added, while stirring and the precipitated product was filtered off with suction. To give 6.4 g (yield 63%) of yellow product which was recrystallized from toluene.
