[0012] 1. Synthesis of poly[(3-octylthiophene)-2,5-bis(4-aminobenzenemethane)] (POTAB): 3.88g (20mmol) 3-octylthiophene and 2.74g (20mmol) 4- Aminobenzaldehyde was dissolved in 50mL dioxane, and 2mL96% concentrated sulfuric acid was added dropwise as a catalyst. 2 Under gas protection conditions, heated to 85 ° C for 30 h. The resulting purple-red reaction solution was poured into 1000 mL of 1M ammonia water for precipitation to obtain a brown solid precipitate, which was filtered and washed with methanol to produce low molecular weight products, and then vacuum-dried at 70°C to constant weight. That is, the POTAB in the intrinsic state is obtained, and the yield is 80%;
