Example Embodiment
[0084] Example: Synthesis of Intermediate
[0085] Synthesis of the intermediate 2-chloro-6-phenylpyridine (1-1)
[0086]
[0087] Synthesis method: 2-bromo-6-chloropyridine (21.2g, 0.11mol), phenylboronic acid (12.2g, 0.10mol), 0.5g tetrakistriphenylphosphorus palladium, add to a 1000ML reaction flask, add 400ML toluene, carbonic acid The sodium aqueous solution (2N, 150 mL) was protected by nitrogen and reacted in an oil bath at 80°C for 24 hours. Post-treatment process: cool down, stand still for 30 minutes to separate liquids, save the organic layer, spin dry toluene, add methylene chloride to the solid to dissolve, pass through the column for separation, PE:DCM=1:1, get A-1(9.6g, y=51%)
[0088] Synthesis of intermediates 1-2 and 1-3
[0089] According to the above-mentioned synthesis method of Intermediate 1-1, the following compounds are obtained:

Example Embodiment
[0125] Example 5 Synthesis of 10-diphenylpyrido[3,2-g]quinoline(6-1)
[0126]
[0127] Add the prepared 5,10-dichloro-pyrido[g]quinoline 5-1 (14.8g, 0.6mmol), 4-boronic acid pyridine (18g, 0.146mmol), and 4g of tetratriphenylphosphine palladium into the reaction flask Add toluene, ethanol and water 2:1:1 (volume ratio) mixed solution totaling 600mL, nitrogen protection, stirring and heating to 110°C for 24 hours. Post-treatment process: cooling system, liquid separation, spin-dry toluene. Add dichloromethane to dissolve the solid, pass the column, and wash with petroleum ether: ethyl acetate=2:1 (volume ratio) to obtain a solid (6-1) (13g, y=65%).

[0128] Synthesis of Examples 6-2~6-17
[0129] According to the synthesis method of Example 6-1 above, the compounds in the following table were obtained:
[0130]
[0131]
[0132]
[0133]
[0134] Example N5, N5, N10, N10-Tetraphenylpyrido[3,2-g]quinoline-5,10-diamine (6-23) synthesis:
[0135]
[0136] According to the synthesis method of Intermediate 1-4, 5,10-dichloropyrido[3,2-g]quinoline (6.0g, 24mmol) and diphenylamine (4.4, 24mmol) were used as raw materials for the reaction to obtain N5, N5, N10, N10-tetraphenylpyrido[3,2-g]quinoline-5,10-diamine (6.17g, y=50%).
[0137] Example 5 Synthesis of 10-bis(1-naphthyloxy)pyrido[3,2-g]quinoline (6-24):
[0138]
[0139] Dissolve 1-hydroxynaphthalene (14g, 0.1mol) in 100mL of anhydrous tetrahydrofuran, stir, accurately weigh NaH (0.96g, 0.4mol) and add them to the reaction flask in batches, not too fast to prevent too many bubbles. After the addition, the solution turned yellow, and then 5,10-dichloropyrido[3,2-g]quinoline (27.50g, ...
