Reaction Conditions

Reaction Steps

Phenyl-p-tolylamine (11.5 g (0.063 mol)), 14.5 g (0.030 mol) of 4,4″-diiodo-p-terphenyl, 5.0 g (0.036 mol) of anhydrous potassium carbonate, 0.38 g (0.006 mol) of copper powder and 15 ml of n-dodecane were mixed, and heated up to 200 to 210° C. while introducing nitrogen gas, followed by stirring for 30 hours. After the termination of the reaction, the reaction product was extracted with 400 ml of toluene, and insoluble matter was removed by filtration. Then, the filtrate was concentrated to dryness. The resulting solid matter was purified by column chromatography (carrier: silica gel, eluent: toluene:hexane=1:4) to obtain 13.6 g of N,N′-diphenyl-N,N′-di-p-tolyl-4,4″-diamino-p-terphenyl (compound No. 17) (yield: 76.4%, melting point: 167.2 to 168.2° C.).
