Selecting phthalocyanine polymorphs using copper iodide
Copper (I) iodide (CuI) thin films are employed as a structural templating layer for the growth of metal-free phthalocyanine (H2Pc) thin films. Structural polymorphs are observed in x-ray diffraction patterns when micro-crystalline CuI films exhibiting copper and iodine terminated grains are used.
