The properties and applications of phthalocyanine (Pc) and its metall derivatives are studied extensively [1-3]. In the recent years special interest attracts to phthalocyanine films in regards with their application in gas sensors. This fact is due to the outstanding features distinguishing these substances from the multitude of other groups of macrocyclic complexes in that they are aromatic macrocycles with a unique conjugated (-system, which determines their chemical and thermal resistance, semiconductor properties and biological activity. It is known that the surface of phthalocyanine films can adsorb molecules of gases to change of physicochemical and optical properties of Pcs. The physicochemical properties (conductivity) and optical characteristics (absorption spectrum) of novel synthesized polyphthalocyanines (PPc), containing Zn, Cu, Mn, Fe, Pb were investigated.
