Abstract

Heteroaromatic oligomer 5,7,12,14-tetrachloro-6,13-diazapentacene (TCDAP) was characterized and assessed as n-channel material in field-effect transistor applications. A single-crystal transistor based on TCDAP as the channel material exhibits a very high electron mobility of 3.39 cm² V⁻¹ s⁻¹ and an on/off ratio of ∼1.08 × 10⁴ respectively.
