✦ Synopsis
A polymorph of perfluoro-vanadyl-phthalocyanine was found to be formed epitaxially on a potassium iodide monocrystalline surface by vacuum deposition. The molecular orientation and molecular packing of the polymorph were analysed by a combination of several electron microscopic methods, namely electron diffraction, high-resolution imaging and electron energy loss spectroscopy. The polymorph is different from the tetragonal polymorph previously obtained on potassium chloride and potassium bromide single crystals. The molecular packing of the new polymorph on potassium iodide was found to be orthorhombic with a = 1.48 nm, b = 0.37 nm and c = 27 nm, the ab-plane being parallel to the substrate surface.
