반응 단계

2.0 g of 1,3,5-tris(1-naphthylamino)benzene, 5.0 g of 4-iodobiphenyl, 3.7 g of potassium carbonate, 2 g of copper powder, 0.3 g of 18-crown-6 (or 1,4,7,10,13,16-hexaoxacyclooctadecane) and 10 mL of mesitylene as a reaction solvent were placed in a 100 mL capacity glass flask and the reaction was carried out at a temperature of 170° C. for 17 hours under a nitrogen atmosphere. After the reaction, the resultant reaction mixture was extracted with toluene and the toluene solution was subjected to silica gel chromatography to fractionate the reaction product. The reaction product was then purified by recrystallization from a mixed solvent of toluene/hexane and then by sublimation to provide 1.2 g of the desired 1,3,5-tris(N-(4-biphenylyl)-N-(1-naphthyl)amino)benzene (TBNAB). The yield was 32%.
