摘要
The title cluster compound [WS4Cu3Br(bipy)2] has been synthesized by the reaction of (NH4)2, CuBr and 2,2′ bipy in DMF solution. Single crystal X ray diffraction data show that the compound has a nest shaped structure. Nonlinear optical properties (NLO) of the cluster were investigated by a Z scan technique with a pulsed laser at 532nm. The cluster exhibits the strong NLO absorption and a self defocusing effect (effective non linear absorption coefficient, α2eff=7.3×10-11mW-1; effective non linear refractive index, n2eff=3.9×10-11esu) when measured in a 6.0×10-4mol·dm-3 DMF solution.

The title cluster compound [WS4Cu3Br(bipy)(2)] has been synthesized by the reaction of (NH4)(2)[WS4], CuBr and 2, 2'-bipy in DMF solution. Single crystal X-ray diffraction data show that the compound has a nest-shaped structure. Nonlinear optical properties (NLO) of the cluster were investigated by a Z-scan technique with a pulsed laser at 532nm. The cluster exhibits the strong NLO absorption and a self-defocusing effect (effective non-linear absorption coefficient, alpha(2)(eff) = 7.3 x 10(-11)mW(-1); effective non-linear refractive index, n(2)(eff) = 3.9 x 10(-11) esu) when measured in a 6.0 x 10(-4)mol (.) dm(-3) DMF solution.
