The synthesis of some N-(p-aminobenzoyl)-L-asparagine derivatives and temperature dependence of the electrical conductivity and Seebeck coefficient for these compounds are studied. The measurements have been performed using the thin-film samples deposited from dimethylformamide solutions of the compounds. All investigated compounds show typical semiconducting characteristics. Some correlation between these characteristics and molecular structure are established. The values of some parameters (activation energy, concentration and mobility of charge carriers, ratio of carrier mobility etc.) of the studied samples have been determined. The nature of the mechanism of electrical conduction is also discussed.
