| Abstract: | The nonlinear optical properties of the fullerene derivative molecule Ir（η5C60 Me5）（CO）2 was studied by density functional theory method. The results show that the molecule structure in relatively high symmetry possess moderately large third-order nonlinear optic response. For the discussion of the origination of the response, the electronic structure was calculated and the UV-VIS absorption spectrum was simulated by TDDFT method. The synergy mechanism of rich d electrons and empty orbital of heavy transition metal and rich n delocalized electrons of fullerene on the third- order nonlinear optical response was announced. |
