Abstract

Axial directional substituting phthalocyanine compound is as semiconductor layer between source / drain electrode of organic thin film transistor (TFT). Central ligand of the phthalocyanine compound is atoms higher than trivalence. Axial ligands are chlorine, fluorin, and oxygen, which can connect to central ligand of the axial directional substituting phthalocyanine compound. Using gaseous phase deposition method prepares high quality crystal film of axial directional substituting phthalocyanine compound on organic substrate easily. Features are: high mobility of carrier of the crystal film, abundant energy levels, stable performance, and easy of integration and process. Mobility of field effect of organic TFT is higher than 0.01cm2 / Vs, and on off ratio is larger than 105.

Description

technical field [0001] The invention relates to the application of an axially substituted phthalocyanine compound for preparing an organic thin film transistor. Background technique [0002] Organic semiconductors with high carrier mobility have promising applications in information display, integrated circuits, photovoltaic cells, and sensors. However, most of the current organic semiconductors show sensitivity to the environment, which brings great difficulties to the integrated processing and application of organic electronic devices. U.S. Patent 5,969,376 discloses the use of planar metal phthalocyanine [copper phthalocyanine (CuPc), zinc phthalocyanine (ZnPc), free phthalocyanine (H 2 Pc), tin phthalocyanine (SnPc)] p-channel organic thin film transistor; 1998 American Chemical Society Journal (J.Am.Chem.Soc.1998,120,207-208) reported the use of planar metal phthalocyanine [Hexadecafluorometallophthalocyanine (F 16 MPc), iron hexadecyl chlorophthalocyanine (Cl 16 Fe...
