Communication
A novel thienoacene-based conjugated oligomer, i.e.BTTT-T-C12, was designed and synthesized. Its highly asymmetric structural feature enables the preparation of two-dimensional single-crystalline thin films in millimetre size and ∼100 nm thick by a solution processing method directly on the Si/SiO2 substrate. Single crystal organic thin film transistors exhibit a mobility of 0.70 cm2 V−1 s−1 and an on/off ratio of 5.7 × 104.
