Description
Summary:[Display omitted] •Two TTF-based small molecules were applied for the construction of OFET.•PY3-based devices exhibited hole mobility of 0.01cm2V−1s−1.•The no OFET performance of PY4-based devices is attributed to poor thin-film morphology and low crystallinity. We report two TTF-based small molecules (PY3 and PY4) in which pyridine acts as an electron withdrawing group for the construction of OFET to investigate the relationship between the FET characteristics and structures. While PY3 thin films demonstrated the highest mobilities up to 0.01cm2V−1s−1, there was no OFET performance for PY4. Atomic force microscope (AFM) and X-ray diffraction (XRD) studies were conducted to gain insight into this dissimilarity.The no OFET performance of PY4 is mainly caused by its poor thin-film morphology and low crystallinity.
