On the electrical properties of some new stable disubstituted ylides in thin films

The synthesis of six new 3-(4-halogenophenyl)-pyridaziniu-(4-chloroanilido)-(4-R-benzoyl)-metylides is described and the temperature dependence of the electrical conductivity and Seebeck coefficient for respective compounds is investigated. The measurements have been performed using thin films deposited from solution. The studied compounds have semiconducting properties. Some correlations between these properties and the chemical structures of the compounds are established. The values of some characteristic parameters of investigated compounds have been determined.
