Example 1Synthesis of Compound Represented by Chemical Formula 9; The compound represented by Chemical Formula 9 as a specific example of an embodiment was synthesized according to the following Reaction Scheme 1. 5 g (0.0135 mol) of material (A), 4.7 g (0.0176 mol) of N-phenyl carbazole boronic acid (material (B)), and 0.78 g (0.7 mmol) of tetrakis(triphenylphosphine)palladium were in suspended in 100 ml of tetrahydrofuran and 100 ml of toluene, and a solution prepared by dissolving 2.8 g (0.02 mol) of potassium carbonate in 100 ml of water was added thereto to form a mixture. The mixture was heated and refluxed for 9 hours. The liquid reactant was separated into two layers, and an organic layer thereof was cleaned with a sodium chloride saturated aqueous solution and dried with anhydrous sodium sulfate.Then, an organic solvent therein was distilled and removed under a reduced pressure, and the residue of the reactant was recrystallized with toluene. The precipitate was filtered and cleaned with toluene, obtaining 8 g of a compound represented byChemical Formula 9 (yield: 90%).
