Recently, polymer semiconducting materials such as organic field-effect transistors(FETs) and organic photovoltaic cells(OPV) have attracted significant attention as a promising alternative to Si-based photodetectors. They have major advantages such as their low-cost processability and mechanical flexibility. Dihydroindoloindole (DINI) derivatives were an electron rich aromatic fused structure with two nitrogen atoms. Furthermore, it can be easily substituted with alkyl chains for better solubility of the polymer. When two electron-rich monomers are polymerized, the one with relatively little electrons becomes the acceptor. In this work, we synthesized indole[3,2-b]indole(IDI) based copolymer for OPVs. |
