Abstract

The invention relates to a perylene tetracarboxylic dianiline conjugated polymer which has high solubility and high film forming processing performance and can effectively utilize sunlight and a preparation method and application thereof. The perylene tetracarboxylic dianiline conjugated polymer utilizes high carrier mobility of thiophene [3,2-b] bithiophene and has the advantage of solution processibility. The thiophene [3,2-b] bithiophene is copolymerized with a narrow-band system monomer diazosulfide unit and perylene tetracarboxylic dianiline so as to regulate a band gap of the polymer. An absorption edge of the perylene tetracarboxylic dianiline conjugated polymer is pushed to an infrared and near-infrared region. Decorated perylene tetracarboxylic dianiline have high solubility, strong absorbance and wide adsorption range and can be extended to the near-infrared region. The sunlight utilization rate of the perylene tetracarboxylic dianiline conjugated polymer is improved. The perylene tetracarboxylic dianiline conjugated polymer has excellent charge transfer performance and has wide application prospect in the fields of an organic solar cell and the like.
