The invention discloses a class of polymers containing S,S-dioxy-dibenzothiophene derivative units and a preparation method and application thereof. In the present invention, S,S-dioxy-dibenzothiophene derivative units are copolymerized with electron-donor monomers to construct polymers with strong electron-donor-acceptor systems, and the prepared polymers have absorption and High carrier mobility. Polymers based on such S,S-dioxy-dibenzothiophene derivative units can be used as active layers in organic/polymer electronic devices such as organic/polymer photodetectors and organic/polymer solar cells. |
