example 1

[0018] Dissolve 0.6 g of 1,4,5,8-tetrahydroxy-9,10-anthraquinone (THAQ) in 160 mL of acetonitrile, then add 6.0 g (NH 4 ) 2 S 2 o 8 , The stirring reaction was continued at room temperature for 16h. Afterwards, the product was filtered, washed with deionized water, and finally washed with acetone until the filtrate was colorless. The obtained dimer product (THHQ) was vacuum-dried at room temperature for 16 h to obtain a black solid powder with a yield of about 80%.

example 2

[0020] Add 0.6g of 1,4,5,8-tetrahydroxy-9,10-anthraquinone (THAQ) into 160mL of ethyl acetate, heat to boiling and add 10.0g of FeCl 3 , Continuous reflux reaction for 20h. The product was then filtered and washed with deionized water to be free of Cl - (with AgNO 3 test), and finally washed with acetone until the filtrate was colorless. The obtained product was vacuum-dried at room temperature for 16 hours to obtain a black solid powder with a yield of about 70%.

example 3

[0022] Add 1.0g of 1,4,5,8-tetrahydroxy-9,10-anthraquinone (THAQ) into 160mL of N,N-dimethylformamide, heat to boil and dissolve it, add 5.0g of KClO 3 , Continuous reflux reaction for 5h. After cooling to room temperature, the product was filtered, washed with deionized water, and finally washed with acetone until the filtrate was colorless. The obtained product was vacuum-dried at room temperature for 16 hours to obtain a black solid powder with a yield of about 75%.

[0023] figure 1 It is the FT-IR spectrum of dimer THHQ (a) and THAQ (b): both are at 3424cm -1 The strong absorption peak of represents the -OH stretching vibration. 1589cm -1 、1598cm -1 They are respectively the stretching vibration peaks of C=O on the aromatic rings of THHQ and THAQ. Due to the enhancement of the conjugation effect, the infrared absorption peak of the group can be blue-shifted, which proves that THHQ has a larger conjugated system than THAQ molecules. For the same reason, the stretchin...

Abstract

The invention relates to a novel quinone compound and a preparation method thereof. The compound has a structural formula which is shown in the specification, wherein n is equal to 4-28; and 1,4,5,8-tetrahydroxy-9,10-anthraquinone is used as a raw material and is subjected to one-step reaction in a solvent in the presence of a catalyst to prepare polyquinone oligomer. The oligomer can be used for a positive material of a high-specific-energy battery and can also be used for a photoelectric device material. The preparation method is simple and practical; a pure product can be obtained without purification; and the yield reaches over 80 percent.

Description

technical field [0001] The present invention relates to a novel organic compound and its preparation method. The compound can be used in the positive electrode material of high specific energy batteries, and can also be used in photoelectric device materials. Background technique [0002] In recent years, lithium-ion batteries have been widely used due to their high specific energy and good cycle performance, and the research on inorganic transition metal compounds for cathode materials has also become a hot spot. From the perspective of sustainable development, this type of cathode material has the following disadvantages when used in future power sources: first, the theoretical specific capacity is low, second, the reserves of raw materials in nature are limited, and third, some of them pollute the environment with heavy metal elements. Compared with inorganic materials, organic cathode materials whose raw materials are drawn from nature can have the advantages of high th...
