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 cm2 V−1 s−1 and a current on/off ratio of 106 in bottom-gate, top-contact thin-film transistors prepared by
