Abstract: | Some nonlinear optical (NLO)-active aromatic azo compounds were selected to be studied in this paper. A series of azo compounds containing different substituent group and different push-pull group were synthesized and their chemical structures were characterized by FT-IR, UV-Vis, elemental analysis and tH NMR, etc.. The third-order NLO properties of azo compounds were measured by single-beam Z-scan technique. The third-order NLO susceptibility of each compound was calculated on the basis of DFT/B3LYP/6-31G quantum chemical method. The influence between the molecular structure and the third-order NLO properties of azo compounds was studied. |
