[0024] A method for preparing a UV-curable branched polythiophene derivative conductive polymer material, the steps of which are as follows:
[0025] (1) Preparation of thiophene derivative monomer: under a nitrogen atmosphere, add 0.06mol glycerol, 60mL of toluene and 1% p-toluenesulfonic acid by weight of the reactant in a three-necked flask of 250mL. 0.12mol of 3-thiophenecarboxylic acid dissolved in 40mL of toluene was slowly added dropwise to the three-neck flask at a rate of 10 drops / minute, and continued to react in an ice bath for 3 hours after the drop was completed, then heated to 100°C, and refluxed for 5 hours; After cooling down to normal temperature, dissolve 0.06mol isophorone diisocyanate and 0.06% stannous chloride based on the weight of the reactant body in 20mL toluene and slowly drop them into the three-necked bottle at a rate of 10 drops / min. Continue to react in an ice bath for 2 hours, then heat up to 50°C, and react for 4 hours; then continue to add 0.0...

[0029] A method for preparing a UV-curable branched polythiophene derivative conductive polymer material, the steps of which are as follows:
[0030](1) Preparation of thiophene derivative monomer: under a nitrogen atmosphere, add 0.06mol trimethylolpropane, 40mL of xylene and 1% tetrabutyl titanate by weight of the reactant to a 250mL three-neck flask , Dissolve 0.12mol of 3-thiopheneacetic acid in 30mL of xylene and slowly drop it into the three-neck flask at a rate of 12 drops / minute. After the drop is completed, continue to react in the ice bath for 4 hours, then raise the temperature to 120°C, and reflux the reaction 6 hours; after cooling down to normal temperature, dissolve 0.06mol isophorone diisocyanate and 0.06% stannous chloride based on the weight of the reactant body in 20mL xylene and slowly drop them into the three-necked flask at a rate of 12 drops / min. After dropping, continue to react in ice bath for 2 hours, then raise the temperature to 50°C, and react for ...

[0033] A method for preparing a UV-curable branched polythiophene derivative conductive polymer material, the steps of which are as follows:
[0034] (1) Preparation of thiophene derivative monomer: Add 8mmol Boltorn H30 dissolved in 50mL methanol to a 100mL three-neck flask under nitrogen atmosphere, and slowly add 10ml of thionyl chloride to the three-necked flask at a rate of 10 drops / min. In the neck flask, after the dropwise addition, react in an ice-water bath for 5 hours, and distill off the solvent under reduced pressure; under ice-water bath conditions and a nitrogen atmosphere, add the first step product and 50mL toluene to a 250ml three-necked flask, and dissolve 0.12mol The 3-thiophenecarboxylic acid dissolved in 20mL of toluene was slowly added dropwise into the three-necked flask at a rate of 10 drops / minute, and continued to react in an ice bath for 5 hours after the drop was completed, then raised the temperature to 90°C, and refluxed for 7 hours; After normal ...
