N1 - Funding Information:
This study was partly supported by Grants-in-Aid (26105004, 17K05976 and 17K05500) from MEXT, and the JST-ACT-C project of the Japan Science and Technology Agency (No. JPMJCR 12YW), and by the Program for Promoting the Enhancement of Research Universities. The XRR measurements at SPring-8 were performed under proposals No. 2017B4133 and No. 2017B4138. The STM measurements were funded by the Ministry of Science and Technology R.O.C. through grants 105-2112-M-007-022-MY3 and 106-2923-M-007-001-MY4.

N2 - 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.
