The annealing of chloroaluminum(III)phthalocyanine (AlClPc) thin films in air results in a chemical transformation to μ-(oxo)bis[phthalocyaninato] aluminum(III) ((AlPc)2O). A comparative analysis of the influence of post deposition annealing process without and under applied magnetic field of 1 T, on the composition and morphology of AlClPc films, has been carried out. The chemical transformation of AlClPc to (AlPc)2O on the substrate surface is studied using UV-vis and Infrared (IR) spectroscopies, Raman, X-ray photoelectron spectroscopy (XPS) as well as atomic force microscopy (AFM). Two interesting effects were observed upon heating the AlClPc films in magnetic field of 1 T: First, the temperature of the chemical transformation of AlClPc to (AlPc)2O decreases from 300 to 200 °C, when magnetic field was applied during post deposition annealing. Second, the formation of (AlPc)2O films with elongated crystallites with a preferential orientation was observed. The heating of (AlPc)2O films in the magnetic field at the same conditions did not demonstrate any effect on structure and morphology of these films.
