The Electrical Conductivity of Heterocyclic Compounds. Molecular Complexes of Phenazine

Some molecular complexes of the salt type have been prepared from phenazinium chloride or methosulfate and pyrene or p-hydroquinone. It has been confirmed that (1) the constitution, the color and the melting point of the molecular complexes varied with the drying conditions; (2) the ultraviolet absorption spectrum of ph-HCl-py by KBr shows a new band at about 620 mμ; (3) an unpaired electron is localized on the nitrogen atom of phenazine, and (4) the electrical conductivities of molecular complexes of the salt type are better than those of the quinhydrone type of phenazine.
