The invention belongs to the technical field of organic semiconductor materials, in particular to an aromatic heterocyclic conjugated polymer based on benzofuranone, a preparation method and application thereof, and an organic field effect transistor. The aromatic heterocyclic conjugated polymer based on benzofuranone provided by the present invention contains 3,6-bis(4-bromo)benzo[2,1-b:3,4-b']difuran-2 ,7-diketone reactive group, which can interact with (4,4,9,9-tetraoctyl-4,9-dihydro-s-didecene[1,2-b:5,6-b'] Dithiophene-2,7-disubstituted) bis(tetramethyltin) constructs a polymer with good planarity, which is beneficial to provide high hole mobility, thereby improving benzofuranone-based aromatic heterocyclic co-polymers. The intermolecular self-assembly and ordering properties of conjugated polymers in the formation of semiconductor thin films are beneficial to obtain better molecular crystals and improve charge transport properties. |
