Abstract: Doping with halide ions is a popular method toalter the properties of metal phthalocyanines (MPcs),particularly magnetic and electrical nature of organic semiconductorsfor applications in spintronic or electronic devices.Doping can cause a structural rearrangement in MPc packing,and the physical properties may be correlated with molecularpacking. Films of a planar and magnetic MPc, manganese-(II)phthalocyanine (MnPc), are chosen for iodine dopingstudy. The optical, magnetic, and electrical properties ofpristine- and iodine-doped MnPc thin films are investigatedand can be directly associated with their molecular structure.Two-dimensional grazing incidence synchrotron X-ray diffractionreveals structural disorder in MnPc films upon iodineinfusion induced by the reorientation of ordered, edge-on molecular configuration to tilted and face-on configurations in arandom fashion. The film morphology changes accordingly, where in the uniform crystallites reorganize in a disordered manner.The ferromagnetic nature of the pristine film gets weakened because of iodine species and favors antiferromagnetic coupling.The study of electrical properties at room temperature by conducting atomic force microscopy reveals that the conductance isenhanced independently of the film thickness because of the disorder induced by iodine inclusion.
