Abstract:
The [10]phenacene and [11] phenacene molecules have been synthesized using a simple repetition of Wittig reactions followed by photocyclization. Sufficient amounts of [10]phenacene and [11] phenacene were obtained, and thin-film FETs using these molecules have been fabricated with SiO 2 and ionic liquid gate dielectrics. These FETs operated in p-channel. The averaged measurements of field-effect mobility, 〈 μ 〉 , were 3.1(7) × 10 −2 and 1.11(4) × 10 −1 cm 2 V −1 s −1 , respectively, for [10]phenacene and [11] phenacene thin-film FETs with SiO 2 gate dielectrics. Furthermore, [10] phenacene and [11]phenacene thin-film electric-double-layer (EDL) FETs with ionic liquid showed low-voltage p-channel FET properties, with 〈 μ 〉 values of 3(1) and 1(1) cm 2 V −1 s −1 , respectively. This study also discusses the future utility of the extremely extended π-network molecules [10]phenacene and [11] phenacene as the active layer of FET devices, based on the experimental results obtained.
