摘　　要：The band gap( E g) and HOMO level 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 HOMO level changed from -5.56 eV to -5.10 eV while the LUMO level changed from -2 68 eV to -2.36 eV with 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.
