Embodiment 1
[0041] The preparation of embodiment 1 sulfonyl ester group anthraquinone derivatives (C01-C16)
[0042] (1) Preparation of 1,4-bis(1,1'-biphenyl)-4-sulfonate)-9,10 anthraquinone (C01):
[0043] Add 0.5 g (2 mmol) of 1,4 dihydroxyanthraquinone, 1.2 g of excess 4-biphenylsulfonyl chloride, and 0.5 g of anhydrous potassium carbonate to a glass flask in sequence, then add 20 mL of anhydrous acetone, and react in an oil bath at 60°C Under reflux reaction, TLC monitors the reaction throughout the whole process. After the reaction is completed, add an appropriate amount of ice water to quench the reaction, filter to obtain a light yellow crude product, and purify it by silica gel column chromatography. Eluent: (dichloromethane:petroleum ether=1:2), The light yellow target compound was obtained with a yield of 74%.
[0044] (2) Preparation of 1,4-bis(2-naphthalenesulfonate)-9,10 anthraquinone (C02):
[0045] Add 0.5g (2mmol) of 1,4-dihydroxyanthraquinone, 1.4g of excess 2-naphthale...
Embodiment 2
[0074] The preparation of embodiment 2 sulfonyl ester group anthraquinone derivatives (C01-C16)
[0075] (1) Preparation of 1,4-bis(1,1'-biphenyl)-4-sulfonate)-9,10 anthraquinone (C01):
[0076] Add 0.1kg of 1,4-dihydroxyanthraquinone, 0.5kg of excess 4-biphenylsulfonyl chloride raw material, 0.1kg of anhydrous potassium carbonate, and then add 4L of anhydrous acetone in a stainless steel reaction kettle, and react in an oil bath at 60°C Reflux reaction, TLC monitors the reaction throughout the whole process, after the reaction is complete, add an appropriate amount of ice water to quench the reaction, filter to obtain a light yellow crude product, purify by silica gel column chromatography, eluent (dichloromethane:petroleum ether=1:2), and obtain pale yellow product Yellow target compound, yield 65%.
[0077] (2) Preparation of 1,4-bis(2-naphthalenesulfonate)-9,10 anthraquinone (C02):
[0078] Add 0.1kg (0.4mol) of 1,4-dihydroxyanthraquinone, 0.5kg of excess 2-naphthalenesu...
