Abstract

HYBRID inorganic-organic nanocomposite materials have ……various electrical and mechanical properties that make them used in many applications in areas of the electronic industry and have played as insulators and dielectrics. Conducting and semiconducting properties have stimulated their use in many novel applications. Among them new symmetrical Lithium phthalocyanine with different lithium concentrations were synthesized by urea fusion technique and characterized through the study of FTIR, and UV-visible spectra. The dielectric properties such as dielectric constant (ɛ`) and dielectric loss (ɛ``) were studied for metal free phthalocyanine and Lithium phthalocyanine complexes with different concentration of lithium ions namely 0.01, 0.03 and 0.06 M. The studies were carried out at frequency range 100Hz-1MHz and within temperature range (280-440 K). It was observed that the dielectric constant of phthalocyanine complexes decrease with the increase of frequency and increase with increasing temperature signifying the semiconducting property. The decrease in energy gap with the coordination of metal ion suggests that the metal ion plays an important role in the electronic properties of the complexes.
