Dielectrical properties and conduction mechanism of quinoline Schiff base and its complexes

The synthesized Schiff base ligand 8-hydroxyquinoline-7-formylidene-4-amino-1-
phenyl-2, 3-dimethylpyrazolin-5-one (SQL) and its Cu (II), VO (IV) and UO 2 (II) complexes
are characterized by various physicochemical techniques. The thermal properties, dielectric
properties, alternating current conductivity (σ ac) and conduction mechanism of SQL and its
complexes (1–6) are investigated in the frequency range of 0.1–100 kHz and temperature
range 298–583 K. The temperature and frequency dependence of the real
