摘要
Disclosed are a S,S-dioxo-dibenzothiophene unit-containing electron donor polymer and the use thereof. The main chain of the electron donor polymer contains a S,S-dioxo-dibenzothiophene unit. By a polymerization method, such as the Stille method, Suzuki method, etc., a novel D-A structure conjugated polymer is constructed. The S,S-dioxo-dibenzothiophene unit has good planarity and high electronegativity. The polymer is endowed with properties, such as a relatively deep HOMO energy level, strong intermolecular interaction, a high light-absorption coefficient, a high mobility and relatively high photoelectric response, so that the related polymer material has wide application prospects in organic solar cells or organic field effect transistor devices.
