Electrical characterization of soluble anthradithiophene derivatives

摘要

Organic semiconductors remain an active subject for device physics and material science because of their varied electrical properties and potential for low-cost, high-throughput roll-to-roll processing. Several high-mobility oligomers, such as pentacene and rubrene, have been identified yet most are incompatible with current manufacturing methods because of issues such as insolubility or poor thin film structure [1–3]. One benefit of working with organic semiconductors is the ability to modify chemical composition to tune both the electrical and physical properties, specifically HOMO-LUMO levels and solubility. Such recently developed organic semiconducting materials are among the forefront of recent advances in the field of organic electronics [3,4]. Organic thin-film transistor electrical characterization of two such newly developed partially fluorinated anthradithiophene (F-ADT) derivatives will be presented.
