제목 Synthesis and Characterization of a Novel NDI-Based Polymer as the Electron Transport Layer for Perovskite Solar Cells
초록 A new naphthalene diimide (NDI)-based polymer with strong electron withdrawing dicyanothiophene (P(NDI2DT-TTCN)) was successfully synthesized by Stille polymerization. NDI is known to have one of the strongest electron-withdrawing backbones and has been proven to have good electron transport properties. Therefore, NDI-based polymers have been extensively applied to the making of organic thin film transistors and organic photovoltaics. In addition, the dicyanothiophene is a strong electron acceptor because of the introduction of the strongly electron withdrawing dicyano group. Moreover, the dicyano-terthiophene has a pseudo-planar structure due to the intramolecular interaction. In this work, it is expected that P(NDI2DT-TTCN) will display good electron transport as well as possess a deep LUMO level that would ensure stable electron transport.
