DC CONDUCTION PHENOMENON AND SPECTRUM OF A NOVEL BIS(7-FORMYL-8-HYDROXYQUINOLINE) ZINC COMPLEX

A novel bis (7-formyl-8-hydroxyquinoline) zinc complex was prepared fr om 7-formyl-8-hydroxyquinoline. This compound was characterized on the basis of elemental analysis, i.r., H-1 nuclear magnetic resonance, ma gnetic moment and conductivity measurements. The compound was a non-co nductor in dimethylformamide. A tentative structure for this compound is suggested. The electrical conductivity at various temperatures for an annealing time of 1 h has been measured. The activation energy of t his compound is found to be 0.68 eV. Conduction parameters including t he Schottky coefficient (beta(S)), Schottky electrode barrier (phi(S)) , jump distance (d) and dielectric constant (epsilon) have been determ ined. The aim of this study is also to understand the mechanism of con duction of this zinc(II) complex.
