It belongs to orthorhombic, space grounp Pnna, with a=1.541 30(5) nm, b=1.884 23 (7) nm, c=2.049 06(7) nm, α=β=γ=90.00°, V=5.950 8(4) nm3, Z=4, Dc=2.427 Mg·m-3 , F (000)=4 132, μ(Mo Kα)=2.568 mm-1. The structure was refined to R1=0.043 5 and wR2=0.122 4 by full-matrix least-squares method. The O atoms of the polyoxometalate, the C atoms of the organic substrates and the O atoms of water molecules are involved in hydrogen bonding. Spectral data support the presence of an electronic interaction between the organic substrate and the inorganic anion in the solid state. It is strongly photochromic under ultraviolet light resulting from charge-transfer. The electrochemical behavior of the compound shows that the redox peak currents are proportional to the scan rate in pH=4.0 NaAc-HAc buffer solution, which indicates that the electrode reaction are surface controlled processes.展开更多

The silicon gel initiator was prepared by self-assemble. Utilizing these modified silicon gel as the substrate, a kind of novel inorganic-organic hybrid material with the polymer metal complex was synthesized. The result of ESR indicates that the inorganic/organic hybrid material with the polymer metal complex based on silicon gel possesses well paramagnetis.展开更多

The organic ligands do not coordinat5e with heteropolyanions, but with Protons in heteropoly acid by coordination bond. Photochromism studies show that the electron transfer takes place from the organic molecules to the heteropolyanions.展开更多
