preparation Embodiment 1
[0102] Preparation Example 1: Synthesis of Intermediate 1 (3,5-dibromobiphenyl)
[0103]
[0104] Under a nitrogen atmosphere, place 6 g of 1,3-dibromo-5-iodobenzene, 2.2 g of phenylboronic acid, 1.5 g of tetrakis (triphenylphosphine) palladium (0) in a 250 mL three-neck round bottom flask, 4.6g of potassium carbonate, 60ml of toluene and 20ml of methanol, and stirred at 65°C for 4hrs. The reaction solution was cooled, followed by extraction with dichloromethane and water, and the extract solution was concentrated. The solution subjected to column chromatography using a mixed solvent of dichloromethane and n-hexane was concentrated to obtain 6.08 g of 3,5-dibromobiphenyl (yield: 71%).

preparation Embodiment 2
[0106] Preparation Example 2: Synthesis of Intermediate 2 (3-(2,6-dibromophenyl)-9-phenyl-9H-carbazole)
[0107]
[0108] Under a nitrogen atmosphere, place 6 g of 1,3-dibromo-2-iodobenzene, 2.2 g of N-phenylcarbazole-3-boronic acid, 1.5 g of tetrakis(triphenyl Phosphine)palladium(0), 4.6g of potassium carbonate, 60ml of toluene and 20ml of methanol, and stirred at 65°C for 4hrs. The reaction solution was cooled, followed by extraction with dichloromethane and water, and the extract solution was concentrated. The solution subjected to column chromatography using a mixed solvent of dichloromethane and n-hexane was concentrated to obtain 3.6 g of 3-(2,6-dibromophenyl)-9-phenyl-9H-carbazole (yield: 56%).
[0109] 1 HNMR (CDCl 3 ,600MHz)δ8.13-8.12(d,1H),7.98(s,1H),7.68-7.66(d,2H),7.63-7.60(m,4H),7.49-7.47(m,2H),7.42- 7.40(m,2H),7.33-7.23(m,2H),7.10-7.071(dd,1H)
preparation Embodiment 3
[0110] Preparation Example 3: Synthesis of Intermediate 3 (3,5-bis(diphenylamine)-1-bromobenzene)
[0111]
[0112] Under a nitrogen atmosphere, place 9 g of 1,3,5-tribromobenzene, 8 g of diphenylamine, 9 g of sodium tert-butoxide, and 0.5 g of tris(dibenzylideneacetone) dipalladium in a three-neck round bottom flask (0), 0.3 g of triphenylphosphine and 200 ml of toluene were dissolved and then stirred while maintaining the temperature at 80°C. After the reaction was completed, the reaction solution was extracted with dichloromethane and water, and concentrated. The solution subjected to column chromatography using a mixed solvent of dichloromethane and n-hexane was concentrated to obtain 5 g of 3,5-bis(diphenylamine)-1-bromobenzene (yield: 35%).
[0113] 1 HNMR (CDCl 3 ,600MHz)δ7.24-7.21(t,8H),7.08-7.06(d,8H),7.02-7.00(t,4H),6.75-6.74(d,2H),6.71-6.70(d,1H)
