文摘

Development of new electron-deficient building blocks is essential to donor–acceptor conjugated polymers. Herein, epindolidione (EPD) as electron-deficient unit was integrated into conjugated polymers for the investigation of field-effect transistors for the first time. We systematically studied the electronic structures and charge transport properties of the EPD-based donor–acceptor polymers. They exhibit p-type transport characteristics with the highest mobility of up to 0.40 cm² V^–1 s^–1, thus demonstrating its great potential as a building block for polymer field-effect transistors and photovoltaics.
