Recently, the D-A polymers based on thieno[3,4-c]pyrrole-4,6-dione (TPD) have received much attention due to its high performance in polymer solar cells and organic thin film transistors. TPD possesses a compact, symmetric, and planar structure, the strong electron-withdrawing imide group, which greatly lowers the HOMO and LUMO energy levels. In this study, we demonstrate the synthesis of new TPD-based copolymers containing thiophene and selenophene moieties as donor monomers. Thermal analysis, cyclic voltammetry and absorption spectroscopy were employed to investigate their physical and molecular electronic properties. Eventually, we fabricated electronic devices to study their p-type semiconducting properties. |
