Paper Abstract

We investigate the relationship between the hybrid form of center metal-atom and the third order nonlinear optical property in a class of 1,3-dithiole-2-thione-4,5-dithiolato-S, S' bis-chelate transition metal complexes for the first time by z-scan. We find that in bis-chelate complexes when the center metal-atom takes the sp3 hybrid form which construct a tetrahedron construction have better third order nonlinear refraction property than in the form of dsp2 hybrid which construct a plane construction and for nonlinear absorption property the case is quite contrary. Cation group have shielding effect on both nonlinear refraction and nonlinear absorption property for this kind of materials.
