New Optical Supramolecular Compound Constructed from a Polyoxometalate Cluster and an Organic Substrate

A new optical supramolecular compound constructed from a polyoxometalate cluster and an organic substrate [(H3O)(C12H10N3)2(PW12O40)] (1) has been synthesized via a hydrothermal reaction and has been structurally characterized by X-ray diffraction. The solid-state diffuse reflectance, IR, and photoluminescence spectra of the title compound indicate that there is an interaction between the α-PW12O40 and the organic substrate. The light-yellow title compound shows a certain second-order nonlinear optical response of I2ω = 2I2ωKDP.
