Abstract
A conjugated polymer containing isoindigo units is disclosed, which has the following structure: P: formula I; wherein, Ar is formula II, formula III or formula IV; R1 is a C8-C20 alkyl; R2 is a C1-C12 alkyl; n is an integer of 2-50. The conjugated polymer containing isoindigo units of this type has good solubility and film-forming property, as well as high thermal stability. HOMO and LUMO energy level are regulated effectively; the absorption range is broaden; and the energy conversion efficiency is greatly improved. A preparation method for the above conjugated polymer containing isoindigo units and use thereof in related fields are also provided.
