A kind of preparation method and application of conjugated macromolecule based on benzodithiophene |
| abstract |
The invention relates to an organic photovoltaic acceptor material, in particular to a preparation method and application of a benzodithiophene-based conjugated macromolecule, and belongs to the technical field of organic semiconductor material preparation. The benzodithiophene-based conjugated macromolecule provided by the present invention has a special molecular structure. Both ends of the side bridge unit are also modified with an alkane chain or an alkoxy chain. The electron cloud density of the conjugated system is increased by benzodithiophene, and the electron donating ability of the central nucleus is improved. At the same time, the introduction of alkyl chains on the bridging unit and thiophene can not only increase the regional flatness of the central core to potentially improve the charge mobility, but also further improve the solubility of the material. |
