Abstract

Fourteen novel complexes of fullerene C60 with metal dialkyldithiophosphate, {[(RO)2PS2]2M}·2C60 (R = Me and Et; M = Mn, Fe, Co, Ni, Cu, Zn and Pd), can be obtained in high yield by the reaction of metal(II) dialkyldithiophosphate complexes with C60 fullerene. Their structures are determined by 1H, 13C, and 31P NMR spectroscopy, elemental analysis, FT-IR and UV-vis, and are supplied by single crystal X-ray data. The compound {[(EtO)2PS2]2Pd}·2C60 was also studied by the HRTEM image and SAED patterns. Studies of the optical properties of the complexes of fullerene C60 with metal dialkyldithiophosphate show that these compounds all have very strong nonlinear optical absorption effects. The nonlinear absorption of fourteen complexes of fullerene C60 with metal dialkyldithiophosphate (in o-dichlorobenzene and in the solid state) was measured by the open-aperture Z-scan technique at a wavelength of 532 nm. DFT calculations are also used to discuss the stability of these complexes and to confirm the structural assignments.
