Donor/acceptor polymers withN-acylated isoindigo as acceptor units have been synthesized. The thermal, optical, electrochemical, and charge-transport properties of the polymers have been investigated. The new polymers show broad absorption from 450 to 900 nm. Due to the strong electron accepting characteristic ofN-acylated isoindigo, the new polymers exhibit narrow optical band gaps and deep LUMO energy levels compared with the polymers based onN-alkylated isoindigo. The new polymers shown-type transport behavior and balanced ambipolar transport behavior in organic thin film transistors (OTFT) device.
