A conjugated polymer containing anthraquinone units has the following structural formula: where -Ar- is: R 1 is a C 1 -C 20 alkyl group; R 2 is a C 1 -C 12 alkyl group; n is an integer of 2-100. The conjugated polymer containing anthraquinone units has good solubility, film-forming properties and high thermal stability, the HOMO and LUMO energy levels are effectively adjusted, the absorption range is widened, and the energy conversion efficiency is greatly improved. . The present invention also provides a preparation method of the above-mentioned conjugated polymer containing anthraquinone units, and points out its application in the fields of solar cells, organic electroluminescence, and organic field effect transistors. |
