Reaction Steps

A mixture of 5 g (14 mmol) of 1-(3-bromophenyl)pyrene, 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(triphenyl phosphine)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 4.95 g (yield 57%) of yellow product which was recrystallized from toluene. MS(m/z, FAB+): 620.1; 1H NMR (CDCl3, 400 MHz): chemical shift (ppm) 9.05 (s, 1H), 8.46˜8.41 (m, 2H), 8.40 (s, 1H), 8.06˜7.84 (m, 9H), 7.74 (d, J=8.00 Hz, 1H), 7.69˜7.59 (m, 4H), 7.54˜7.39 (m, 5H), 7.31˜7.16 (m, 3H), 1.82 (s, 6H).
