title: A core-extended naphthalene diimide as a p-channel semiconductor.
abstract: A novel naphthalene diimide with a fully conjugated, extended π-core was synthesized in a one-pot, two-step reaction. This organic semiconductor exhibits ambipolar transport properties with a large hole mobility of 0.56 cm(2) V(-1) s(-1) and a current on/off ratio of 10(6) in bottom-gate, top-contact thin-film transistors prepared by vacuum deposition.
