High-performance organic field-effect transistors based on single and large-area aligned crystalline microribbons of 6,13-dichloropentacene.

Single and large-area aligned crystalline microribbons of 6,13-dichloropentacene (DCP) are prepared. The ribbons display excellent charge transport properties with a mobility of up to 9.0 cm(2) V(-1) s(-1) in ambient conditions, one of the highest values reported for organic semiconductors. The slipped π-π stacking with large intermolecular overlap is responsible for the high mobility of DCP ribbons.
