Phthalocyanine Composites as High‐Mobility Semiconductors for Organic Thin‐Film Transistors

Abstract

A new class of organic semiconductors based on composites of copper phthalocyanine and nickel phthalocyanine for use in organic thin-film transistors show relatively high mobilities. X-ray diffraction of the composite films, which consist of homogenously sized crystals (see Figure), indicates the presence of a new crystalline phase incorporating both copper and nickel phthalocyanine molecules.
