Embodiment 1

[0044] A preparation method of an organic-inorganic hybrid polymer, the specific synthesis steps are as follows:

[0045]2,5-diamino-1,4-benzenedithiol dihydrochloride (245.2 mg, 1 mmol) was dissolved in DMF (50 mL), and dry nitrogen was passed through for 5 hours to remove dissolved oxygen in the solvent, and then Zinc dichloride (136.3 mg, 1 mmol) was dissolved in deionized water (50 mL) and added dropwise to the above solution at 0 °C. Then the reaction system was adjusted to neutrality (pH = 7) by adding ammonia water dropwise. Finally, it was stirred at room temperature for 6 h. After the reaction, a black solid was formed. The reaction solution was evaporated under reduced pressure to remove the solvent, and then the solid was washed with water and acetone respectively. After repeating the above steps three times, it was dried in a vacuum oven at 70°C for 12 hours, and finally a brown powder product was obtained. Organic-inorganic hybrid polymer, denoted as Zn-DABDT. ...
