Title:
ORGANIC POLYMER HAVING ASYMMETRIC STRUCTURE AND USE THEREOF AS PHOTOELECTRIC MATERIAL
Document Type and Number:
WIPO Patent Application WO/2021/143316
Kind Code:
A1
Abstract:
Provided are an organic polymer having an asymmetric structure, a preparation method therefor and use thereof as a photoelectric material. The organic polymer having the asymmetric structure is obtained by polymerizing an electron-donating D unit and an electron-withdrawing A unit by means of a Stille coupling reaction in the presence of a solvent and a catalyst. The organic polymer having the asymmetric structure has excellent thermal stability and controllable absorption energy level, and is suitable for preparing high-performance perovskite battery hole materials and organic solar cell donor materials with high efficiency, good stability, flexibility and large area.
