| abstract |
The invention discloses an organic small molecule semiconductor material containing anthracenedithiophene and its preparation method and application. The structural formula of the material is shown in formula I, wherein, A unit is an electron-deficient group; R1 is hydrogen, or It is an alkyl group with 1-30 carbon atoms, or one or more carbon atoms in the alkyl group with 1-30 carbon atoms are replaced by a halogen atom, an oxygen atom, an alkenyl group, an alkynyl group, an aryl group, a hydroxyl group , Amino, carbonyl, carboxyl, ester, cyano or nitro substitution groups. The material has unique advantages such as good light-harvesting ability, suitable electron energy level, and high electron mobility. It is used as an electron acceptor material in organic solar cell devices to obtain good device performance. |
