Embodiment 1
[0075] Under argon protection, in a 100ml round bottom flask, 0.1mol of the ligand shown in structural formula L1 (purchased from Alfa Aesa (Alfa Aesa Chemical Co., Ltd.)) was dissolved in ethylene glycol diethyl ether as a solvent, Under the protection of low temperature (-2 to -5 degrees), add 0.05mol butyllithium as a catalyst, stir for 30 minutes and add 0.1mol anhydrous IrCl to the mixed solution 3 After stirring again for 30 min, the mixed solution was heated to reflux at 80-130°C for 24 hours and cooled to room temperature, then 0.2mol of auxiliary ligand acetylacetone was added thereto, and heated to reflux at 80-130°C for 24 hours and cooled to room temperature , then use a rotary evaporator to carry out vacuum concentration to remove the organic solvent and obtain a crude product, use methyl chloride / n-hexane 5:1 as the mobile phase to carry out column chromatography purification of the obtained crude product, and obtain 0.08mol after vacuum drying at 50°C As the fin...

[0082] Under argon protection, in a 100ml round bottom flask, 0.1mol of the ligand shown in structural formula L2 (purchased from Alfa Aesa (Alfa Aesa Chemical Co., Ltd.)) was dissolved in ethylene glycol diethyl ether as a solvent, Under the protection of low temperature (-2 to -5 degrees), add 0.05mol butyllithium as a catalyst, stir for 30 minutes and add 0.1mol anhydrous IrCl to the mixed solution 3 After stirring again for 30 min, the mixed solution was heated to reflux at 80-130°C for 24 hours and cooled to room temperature, then 0.2mol of auxiliary ligand acetylacetone was added thereto, and heated to reflux at 80-130°C for 24 hours and cooled to room temperature , then use a rotary evaporator to carry out vacuum concentration to remove the organic solvent and obtain a crude product, use methyl chloride / n-hexane 5:1 as the mobile phase to carry out column chromatography purification of the obtained crude product, and obtain 0.08mol after vacuum drying at 50°C As the fin...
Embodiment 3
[0089] Embodiment 3 (self-phase polymerization reaction of M1 monomer)
[0090] Under argon atmosphere, add the monomer shown in the structural formula A to the toluene solution, then add AIBN (azobisisobutyronitrile) as an initiator, polymerize at 40-120°C for 0.5-5 hours, and the reaction ends rear. Add methanol to precipitate the product, then add toluene to dissolve, then add methanol, and repeat the purification in this way to obtain a polymer represented by the following formula, wherein n is 20-200:
