Abstract

A cyclic triphenylamine dimer with high crystallinity is demonstrated. Micrometer- and nanometer-sized single-crystalline ribbons are easily produced by a physical vapor transport technique. Field-effect transistors of the ribbons exhibit mobilities up to 0.05 cm2 V−1 s−1. The mobility of the devices depends greatly on the size of the ribbons: the smaller the ribbons, the higher the mobility.
