AbstractCorrelation of the molecular structure and thermal study of the electrical conductivity of benzaldazine (BA) and its NO 2-derivatives were carried out. The values of the activation energies, obtained from the electrical conductivity measurements, as well as the energy gaps calculated from ultra violet (u.v.) and visible spectra obtained either in liquid or in solid forms indicate that all compounds behave like a semiconducting material. Both nπ*′s and ππ*′s were found to be the main sources participatiog in the cooduction processes. © 1991 Chapman and Hall Ltd.
