Synthesis, Spectral Properties of Zinc Hexadecafluorophthalocyanine (ZnPcF₁₆) and Its Application in Organic Thin Film Transistors

抄録

A stable n-type semiconductor material, ZnPcF₁₆, was synthesized and characterized by infrared (IR), UV-vis and fluorescence spectra. ZnPcF₁₆ showed a monomer characteristic in 1, 2-dichlorobenzene (DCB) while exhibited an aggregation property in tetrahydrofuran (THF) and dimethylformamide (DMF). The ZnPcF₁₆/p-6p (ZnPcF₁₆ on p-6p) organic thin film transistors (OTFTs) using ZnPcF₁₆ as an active layer and p-6p as an inducing layer was fabricated by the physical vapor deposition technique. The ZnPcF₁₆ semiconductor film was characterized by XRD and SEM. And the results showed that ZnPcF₁₆ molecules can be oriented after the employment of the p-6p inducing layer. Charge carrier field-effect mobility (µ) and threshold voltage (V_T) of the ZnPcF₁₆/p-6p OTFTs were 1.3 × 10⁻² cm²/V s and 22 V, respectively.
