The growth of rubrene thin films thermally evaporated under ultra‐high vacuum (UHV) on SiO 2 has been investigated by combining atomic force microscopy (AFM), scanning electron microscopy (SEM), and polarized optical microscopy (POM) techniques. A mode of thin film growth in which an amorphous continuous holy film first covers the substrate, and acts afterwards as a template for the nucleation of polycrystalline rubrene spherulites, has been identified. Additionally, rubrene one‐dimensional structures have been observed with a catalyst‐free growth process. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
