Abstract

Abstract: The band gap( E_g) and HOMOlevel of pyrazoline derivative were obtained by UV-Vis absorption spectra and electrochemical cyclic voltammetry methods. The effect of the molecular structure of pyrazoline on the energy band structure was investigated. It was indicated that the HOMOlevel changed from -5.56 eVto -5.10 eVwhile the LUMO level changed from -2.68 eVto -2.36 eVwith different substituents in pyrazoline derivatives. The results obtained showed that the energy band structure of pyrazoline derivatives could be adjusted through changing the molecular structure.

Key words: Pyrazoline derivatives, Electrochemistry, Energy band structure
