Structure and morphology of cobalt phthalocyanine (CoPc) organic film on silicon dioxide (SiO₂) — •Monamie Sanyal — Max Planck Institute for Metals Research, Heisenbergstrasse 3, Stuttgart - 70569, Germany

Phthalocyanines (Pc) are of great interest as functional molecular building blocks for organic electronics, partly on account of their enormous versatility and because of their unusually high chemical and thermal stabilities. In order to optimize their functional properties, the detailed knowledge of their film structure is a prerequisite. So far, majority of the investigations have been carried out on metal free phthalocyanine (H₂Pc) and its metal derivative (CuPc). Cobalt phthalocyanine (CoPc) is interesting for applications in optoelectronics and additionally is considered for application as a low dimensional molecular magnet due to magnetic properties of Co ion.

Here we show that CoPc on SiO₂ /Si forms very well ordered multilayer films of standing molecules. By combining x-ray diffraction studies and Atomic Force Microscopy (AFM) we present results on the structure (perpendicular and parallel to the film surface) and morphology.
