2.27 g (0.008367 mol) of 1-(9H-carbazol-2-yl)benzaldehyde, 4.0 g (0.010 mol) of 9-(4′-bromobiphenyl-4-yl)-9H-carbazole, 3.79 g of Cu bronze, 0.53 g (0.00294 mol) of 1,10-phenanthroline and 11.39 g (0.082 mol) of potassium carbonate are initially introduced. The solids are dissolved in 53 ml of 1,2-dichlorobenzene and stirred under reflux for 2 days. After filtration through Celite, the mixture is evaporated to dryness. Column chromatography with toluene/hexane as eluent give 2.4 g (49%) of clean product.
