Isolation and Characterization of the Unexpected 1‑<i>n</i>‑Octyloxyperopyrene: A Solution-Processable p‑Type Organic Semiconductor

The synthesis and optical, electrochemical, thermal, and electrical characterization of a new and unexpected 1-n-octyloxyperopyrene is reported. The structure of 1-n-octyloxyperopyrene has been unambiguously established by single-crystal X-ray diffraction. The solubility of this polycyclic aromatic hydrocarbon, endowed by the alkoxy substituent, allows the fabrication of thin-film field-effect transistors by liquid deposition methods. These devices show hole mobilities up to 1.61 × 10–3 cm2 V–1 s–1.
