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 the𝑝p-6p inducing layer,the performance of the CuPcF16/𝑝p-6p OTFTs is greatly improved.The charge carrier field-effect mobilityμ,on-off current ratio𝐼Ⅰon/Ⅰoff and threshold voltage𝑉VT of the CuPcF16/p-6p OTFTs are 0.07 cm^(2)/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 of𝑝p-6p to form a highly oriented and continuous film of CuPcF16 with the molecularπ–πstack direction parallel to the substrate.
