摘要

Two enantiomerically pure polytungstates, Na₂[(CH ₃)₂NH₂]₃{Na[Ce^III(H ₂O)(CH₃CH₂OH)(l-tartH₃)(H ₂Si₂W₁₉O₆₆)]}·3.5H ₂O (l-1) and [(CH₃)₂NH₂] ₇{Na[Ce^III(H₂O)(CH₃CH ₂OH)(d-tartH₃)(Si₂W₁₉O ₆₆)]}·2.5H₂O (d-1), were successfully synthesized. Structural analysis indicates that chiral tartrate ligands directly connect with novel lacunary [Si₂W₁₉O₆₆]^10- polytungstate units. Strong induced optical activity in the polyoxometalate (POM) units is manifested by circular dichroism spectroscopy. Z-scan analysis revealed that l-1 and d-1 are the first chiral POM-based complexes that exhibit two-photon absorption properties typical of the third-order nonlinear optical response.
