A new potential non-linear optical (NLO) organic material 1-ferrocenyl-3- (4-dimethylaminophenyl) propenone (FDAK) was synthesized and characterized by 1H NMR, IR, MS and elemental analysis Characterization. The third-order nonlinear optical properties of the title compound were determined and the relevant parameters were determined by powder Nd: YAG laser. The results of nanosecond experiments showed that the refractive index n2 = -1.9 × 10-17 m2 / W, the absorption coefficient β = -7.7 × 10-11 m / W, the polarizability χ (3) = 1.07 × 10-11 esu, Polarization rate γ = 4.67 × 10-31 esu; picosecond experimental results: n2 = 2.5 × 10-19 m2 / W, β = -5.9 × 10-12 m / W, γ = 1.13 × 10-31 esu, χ (3) = 2.0 × 10-13 esu. The thermal stability of the target compound is seen in the DSC curve.
