摘要We demonstrate n-type organic thin film transistors (OTFTs) employing copper hexadecafluorophthalocyanine (CuPcF16) as the active layer and para−hexaphenyl (p−6p) as the inducing layer. Compared with the CuPcF16−based OTFTs without the p−6p inducing layer, the performance of the CuPcF16/p−6p OTFTs is greatly improved. The charge carrier field-effect mobility μ, on−off current ratio Ion/Ioff and threshold voltage VT of the CuPcF16/p−6p OTFTs are 0.07 cm2/V⋅s, 1.61×105 and 6.28 V, respectively, approaching the level of a single crystal device. The improved performance is attributed to the introduction of p−6p to form a highly oriented and continuous film of CuPcF16 with the molecular π–π stack direction parallel to the substrate.
