【Abstract】 A series of azobenzene compounds with″ push-pull″ structure have been studied by analyzing the EI mass spectra. The results show that main fragmentation pattern of the compounds was governed by their resonant structure. Azo group will adhere to the group which donated electron, when an internal hydrogen bond is presented in the molecule of the compounds, and succeeding fragmentation pattern is determined by presenting main functional group.更多还原
