Two
enantiomerically pure polytungstates, Na2[(CH3)2NH2]3{Na⊂[CeIII(H2O)(CH3CH2OH)(l-tartH3)(H2Si2W19O66)]}·3.5H2O (l-1) and [(CH3)2NH2]7{Na⊂[CeIII(H2O)(CH3CH2OH)(d-tartH3)(Si2W19O66)]}·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.
