In the present work, phthalocyanine nanowires were obtained on the surface of glass substrates with an ITO coating. The presence of α, β, and χ crystalline phases, which are formed in the course of synthesis was demonstrated using XRD. Measurement of the absorption spectra showed that the observed change in the shape of the absorption bands is associated with the formation of phase states and the relationship between the tendency of the central metal ion to leave the phthalocyanine plane and the value of the Davydov splitting. It was found that the high-value conductivity of the nanowires is explained by the possibility of the π-electrons transition depending on the metal ion, over the states of overlapping phthalocyanine rings. An analysis of the obtained results showed that additional energy states are involved in the charge transfer mechanism, which is formed during the coordination interaction of metal ions with an organic ligand.
