High-Performance Air-Stable Ambipolar Organic Thin-Film Transistor Based on F16CuPc and CuPc

We report on the fabrication of organic thin-film transistors based on fluorinated copper phthalocyanine (F16CuPc) and copper phthalocyanine (CuPc) layers. The thin-film transistors showed high-performance air-stable ambipolar characteristics with a field-effect hole mobility of 3.26 ×10-3 cm2/V·s and a field-effect electron mobility of 3.34 ×10-3 cm2/V·s, which are comparable to the unipolar field-effect mobilities of single-layer thin-film transistors. These outstanding ambipolar characteristics, along with the highly stable chemical nature of F16CuPc and CuPc, make this transistor an attractive candidate for organic complementary metal oxide semiconductor (CMOS) circuits.
