Abstract

Electrical conductivity of some dibenzoylmethane arylhydrazones (DBMAH) were measured during heating and reheating runs. The observed variation of the conductance of the polycrystalline sample during thermal agitation was found to depend on the ordering and disordering of molecules which in turn cause the lattice dipole to distort. A semiconducting behavior was detected for these systems as it was deduced from their conductance values (1.7 × 10−6 − 8.25 × 10−7 ohm−1 cm−1). The presence of substituents affects markedly the measured electrical conductivity and calculated activation energy values.
