The synthesis of 4 - [(1E) -2- (benzothiazol-2-yl) ethenyl] -N, N-dimethyl (2-methylbenzothiazole and 4-dimethylaminobenzaldehyde) Aniline was measured by 4f coherent imaging technique at a wavelength of 480nm and a pulse width of 4ns. The third-order optical nonlinear parameters were measured with nonlinear absorption coefficient β = -1.78 × 10-9 m / W, nonlinear refraction Rate n2 = -0.15 × 10-16 m2 / W, the third-order nonlinear polarizability χ (3) = 3.86 × 10-11 esu, and the UV-Vis absorption spectra, fluorescence spectra and DSC curves were measured. Experiments show that the compound has good thermal stability and third-order nonlinear optical properties.
