Embodiment 1

[0029] In a 100mL three-necked flask, 60mL of acetic acid was added, while 2,3-diamino-1,4-dimethoxybenzene (0.756g, 4.5mmol), cyclohexanone decahydrate (0.522g, 1.5mmol) were added , under the protection of nitrogen, the reaction mixture was continuously stirred in the reflux state. The reaction time was 48 hours. After the reaction, stop heating, add water to precipitate the brown solid product, collect the solid by suction filtration, wash with water and ethanol for several times, and vacuum at 80 ° C. After drying for 6h, Compound A: 1,4,7,10,13,16-hexamethoxydiquinoxaline phenazine was obtained. figure 1 is the infrared spectrum, figure 2 is the H NMR spectrum, image 3 is the carbon NMR spectrum, Figure 4 for the mass spectrogram.
