Study on Structural and Dielectrical Properties of some Chloroquinoxaline Derivatives
The structural, thermal and electrical properties of three chloroquinoxaline derivatives are investigated by X-ray diffraction (XRD) and differential scanning calorimetric (DSC) techniques. It is found that the chemical composition affected the structure and thermal stability of each derivative. The dielectric properties of the three derivatives are investigated in the frequency range 100 Hz 5MHz and in the temperature range 300 470 K. The behaviors of the real and imaginary parts of the dielectric constant is investigated. Also, the AC conductivity as a function of both temperature and frequency is studied. The charge carrier’s conduction mechanism is found to follow the quantum mechanical tunneling (QMT) model. The complex bulk modulus is also investigated.
