Synthetic example 1
[0131] Substituent introduction reaction
[0132] A mixed solution of 34 g (0.1345 mol) of naphthalene-2.6-dicarbonyl dichloride, 62.4 g (0.269 mol) of methoxypyrene, and 496 g of 1,2-dichloroethane / chloroform was placed in the flask. Next, 35.8 g (0.269 mol) of aluminum chloride was slowly added to the solution, and the resulting mixture was stirred at room temperature for 12 hours. When the reaction was complete, methanol was added thereto and the precipitate generated therein was filtered and dried.
[0133] Addition reaction
[0134] 6.4 g (10 mmol) of the compound obtained from the reaction and 285 g of tetrahydrofuran were placed in a flask, 20 ml (40 mol) of benzylmagnesium chloride (2.0 M in THF) was slowly added thereto at 0° C., and the mixture was heated to room temperature and stirred for 24 hours. When the reaction was completed, the resultant was neutralized with 5% hydrochloric acid solution to around pH 7, and then extracted with ethyl acetate and dried to o...

[0138] Substituent introduction reaction
[0139] According to the same method as Synthetic Example 1, 28 g (0.1 mol) of benzoperylene, 46 g (0.21 mol) of 6-methoxy-2-naphthoyl chloride, 29 g (0.22 mol) of aluminum chloride and 707 g of dichloromethane were reacted .
[0140] Addition reaction
[0141] According to the same method as in Synthesis Example 1, using 6.4 g (10 mmol) of the compound obtained from the reaction and 12.5 ml (25 mmol) of isopropylmagnesium chloride (2.0 M in THF), the compound represented by Chemical Formula B was obtained.

[0145] Substituent introduction reaction
[0146] Put 20.2g (0.1mol) terephthaloyl dichloride, 11.6g (0.05mol) 4-methoxypyrene, 7.9g (0.05mol) methoxynaphthalene and 157g 1,2-dichloroethane in the flask . Next, 13.2 g (0.1 mol) of aluminum chloride was slowly added to the solution, and the mixture was stirred at room temperature. The reaction was complete when the weight average molecular weight of samples taken from the polymerization reactants every hour was in the range of 1,200 to 1,500. When the reaction was completed, a precipitate generated by adding methanol thereto was filtered, and monomers remaining therein were removed with water and methanol, obtaining a polymer represented by Chemical Formula C (Mw: 1500).
