Thiophene backbone-based polymers with electron-withdrawing pendant groups for application in organic thin-film transistors

Two thiophene backbone-based hole-transporting polymers, namely, poly[(2,2′-bithiophene-5,5′-diyl)- alt -(5,7-bis(2-butyloctyl)-4 H ,8 H -benzo[1,2- c :4,5- c ′]dithiophene-4,8-dione-1,3-diyl)] ( PT2-BDD ) and poly[(3,3′-difluoro-[2,2′-bithiophene]-5,5′-diyl)- alt -(5,7-bis(2-butyloctyl)-4 H ,8 H -b...
