Abstract:Three new lanthanide-supported molybdovanadates [Ln(H2O)(5)](2)Mo6V2O26 center dot 8H(2)O (Ln - La 1; Ce 2; Nd 3) have been synthesized by the reaction of the [Mo6V2O26](6-) anion with Ln(NO3)(3) in aqueous solution and characterized by elemental analysis, IR, solid state UV-vis spectroscopy, thermal gravimetric analysis, powder X-ray diffraction and single-crystal X-ray diffraction. Compounds 1-3 are obtained at the same pH value (3.0) and have similar structural units which consist of one molybdovanadate unit supported by two lanthanide cations. Then, these bi-supporting subunits are joined together by strong hydrogen-bonding interactions between polyoxoanions and coordinated water molecules to form a 3D supramolecular framework. To the best of our knowledge, they represent the first examples of inorganic species constructed from molybdenum-vanadium polyoxometalates and lanthanides. The UV-vis diffuse reflectivity spectra of 1-3 show that they can be regarded as a wide gap semiconductor. Photocatalytic studies indicate that compounds 1-3 are not only active photocatalysts for degradation of rhodamine B, but very stable and easily separated from the photocatalytic system for reuse as well. Moreover, the new materials were tested as catalysts in cyanosilylation reactions of aldehydes under solvent-free conditions. The experimental results indicate that all three compounds 1-3 can act as Lewis acid-base catalysts through a heterogeneous manner to prompt cyanosilylation with good efficiency.
In 2002, Prof. Haiyan An received the B.S. degree in chemistry Northeast Normal University, Changchun, China; the M.S. in 2004 and the Ph.D. degree in 2007 in Key Laboratory of Polyoxometalates (POMs) Science of Ministry of Education. There were 30 papers published in Angew. Chem. Int. Ed., Inorg. Chem., Cryst. Growth Des., etc. during the degree. In 2006, she was awarded the Excellent Doctoral Dissertations Fund of Northeast Normal University. In July 2007, Prof. An joined College of Chemistry, Dalian University of Technology in the field of POMs. Her research interests are mainly focuse on the design, synthesis and properties’research of POM-based functional complexes with catalytic and drug activity. She has Undertaked two National Natural Science Foundation of China, one Specialized Research Fund for the Doctoral Program of Higher Education, one Natural Science foundation of Liaoning Province and one Scientific Research Foundation for Doctor of Liaoning Province. There are more than 30 SCI papers have been officially published in foreign periodicals during the work period, more than 20 of which list her as the first author and corresponding author.
