Embodiment 1
[0032] A kind of synthesis of bis-azodiphenyl sulfone compound with symmetrical structure, its general formula is:
[0033]
[0034] When R1 is a methyl group, its synthesis steps are as follows:
[0035] (1). Weigh 5 mmol of 4,4'-dimethylaminodiphenyl sulfone and add it to the mixed solution of 10-30 mL of N, N-dimethylformamide and 3-10 mL of concentrated hydrochloric acid and cool the reaction system When the temperature is below 10°C, prepare 0.4-0.8g / mL sodium nitrite ice water solution and slowly add it dropwise to the aforementioned reaction system. After the reaction solution becomes clear, continue to stir for 20-120 minutes, filter, and freeze the filtrate for storage;
[0036] (2). Weigh 8-12mmol of N,N-dimethylaniline and dissolve it in 5-15mL of N,N-dimethylformamide, and slowly add the solution dropwise to step (1) at 10°C In the diazonium salt solution, stir and react for 20-120 minutes, adjust the pH value of the system to 5-7, continue to stir and react fo...
Embodiment 2
[0060] A kind of synthesis of bis-azodiphenyl sulfone compound with symmetrical structure, its general formula is:
[0061]
[0062] When R is a methoxyl group, its synthesis steps are as follows:
[0063] (1). Weigh 5 mmol of 4,4'-dimethylaminodiphenyl sulfone and add it to the mixed solution of 10-30 mL of N, N-dimethylformamide and 3-10 mL of concentrated hydrochloric acid and cool the reaction system When the temperature is below 10°C, configure 0.4-0.8g / mL sodium nitrite ice water solution and slowly add it dropwise to the aforementioned reaction system. After the reaction solution becomes clear, continue to stir for 20-120 minutes, filter, and freeze the filtrate for storage;
[0064] (2). Weigh 8-12mmol of methoxybenzene and dissolve it in 5-15mL of N,N-dimethylformamide, and slowly add the resulting solution dropwise to the diazonium salt solution in step (1) at 10°C , stir and react for 20-120 minutes, adjust the pH value of the system to 5-7, continue to stir and...
Embodiment 3
[0085] Taking the compound (A1) obtained in Example 1 as an electrical storage active material as an example, an electrical storage device with a sandwich structure was prepared. The production procedure was as follows: the ITO conductive glass (6) was cleaned with water, acetone, and isopropanol in ultrasonic waves for 5 After ~30 minutes, place it in a vacuum coating machine as an organic material deposition substrate; take 20-30 mg of compound (A1) in a quartz crucible and place it in the molybdenum boat of the vacuum coating machine, and evacuate until the internal pressure of the coating machine is less than 3× 10 -3 Pa begins to vapor-deposit organic molecules, and the organic film thickness is controlled between 60-100nm by a film thickness detector; A certain amount of aluminum wire is hung on the tungsten wire, and the vacuum is evacuated again until the vacuum degree in the coating machine is less than 8×10 -4 Pa, start to heat the tungsten wire to vapor-deposit alu...
