5.0 g of 9H-carbazole (3.0 10−2 mol), 0.67 g of CuI (3.2 10−3 mol), 10.0 g of K2CO3 (7.2 10−2 mol), 1.16 g of 1,10 phenanthroline (6.4 10−3 mol), and 9.36 g of 4,4′-dibromobiphenyl (3.0 10−2 mol) are initially introduced. After addition of 200 ml of DMF, the reaction mixture is stirred under reflux for 12 h. After filtration through Celite with suction, it is precipitated using water and filtered off with suction. The solid is dissolved in hot THF and precipitated using ethanol, giving 7.7 g (64%) of clean substance.
