Abstract Experimental data relating to the temperature dependence of the electrical conductivity of aromatic organic compounds are discussed within the framework of the zone (band) model. The electrical conductivity of these compounds is determined by the bond energy of the molecular compounds and diminishes with increasing melting point. The Mott formula is satisfied for anthracene, phenanthrene, and naphthalene, while the dependence of σs/σl on the change in thermal activation energy established by Gubanov for inorganic semiconductors also applies to those organic semiconductors for which δε is equal to or less than 2 eV. An analysis of the experimental data indicates than zone (band) theory may be used for organic semiconductors in the melting region if the character of the conductivity is similar in the solid and liquid states and the change in thermal activation energy is small.
