A bowl-shaped sumanene derivative with dense convex–concave columnar packing for high-performance organic field-effect transistors†
Abstract
The charge transport properties of a bowl-shaped sumanene derivative with dense convex–concave columnar packing were studied. Single-crystal microribbons were grown by solution casting. Organic field-effect transistors based on individual single-crystal ribbons displayed a high hole mobility up to 0.37 cm2 V−1 s−1, which was one of the highest mobilities for buckybowl aromatics.
