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.
