The effects of annealing process influence on optical properties and the molecular orientation of selected organometallic compounds thin films

► PVD technique for thin films of MPc (M = Zn, Co, Cu, Mg) and MClPc (M = Al, Ga). ► Absorbance analysis as a function of the annealing process temperature. ► Physical dimer theory of molecular arrangement after annealing process. ► Davydov splitting and resonance interaction energy.
