Abstract

In this paper are reported the electrical properties of four mixtures of two products: (1) 4-phenyl 1,2,4-triazol-1-ium benzoyl 2,4,6-trinitrophenyl methylide and (2) 4-phenyl 1-phenacyl 1,2,4-triazol-1-ium bromide. The experiments have been performed in a general assembly composed by an impedance analyzer and a heating system driven by a computer. All analyzed mixtures show semi conducting properties. The theoretical model based on calculated transfer energies using PM3, B88 LYP DFT and Gaussian B3 LYP 6–31 G (d) methods suggests the presence of salt cation S+ as a doping agent of the type “P”.
