Abstract:Six novel organic-inorganic hybrid polyoxometalate derivatives, K[(H2O)(4)(3-Hpic)(2)Ce][(H2O)(5)(3-Hpic)(2)Ce] [PW10Ti2O40]center dot 11H(2)O 1, K[(H2O)(4)(3-Hpic)(2)Nd][(H2O)(5)(3-Hpic)(2)Nd][PW10Ti2O40]center dot 12H(2)O 2, K[(H2O)(4)(3-Hpic)(2)Sm][(H2O)(5)(3-Hpic)(2)Sm][PW10Ti2O40]center dot 8H(2)O 3,H[(H2O)(7)(4-Hpic)La][(4-Hpic)(2)LaPW11O39]center dot 14.5H(2)O 4, H[(H2O)(7)(4-Hpic)Ce][(4-Hpic)(2)CePW11O39]center dot 7.5H(2)O 5, and K(4-Hpic)(0.5)[(H2O)(6)(4-Hpic)Nd][(4-Hpic)(2) NdPW11O39]center dot 10H(2)O 6, (3-Hpic = 3-picolinic acid; 4-Hpic = 4-picolinic acid) have been synthesized and characterized by elemental analysis, IR, solid state UV-vis spectroscopy, thermal gravimetric analysis, powder X-ray diffraction and single-crystal X-ray diffraction. Isostructural compounds 1-3 are hybrid dimers that consist of two Ti-substituted Keggin-type polyoxoanions [PW10Ti2O40](7-) and four Ln-3-Hpic coordination groups. The strong hydrogen bonds in 1-3 can make these dimers yield a 1D supramolecular chain. Compounds 4-6 are also dimers constructed from two lanthanide-substituted Keggin-type polyoxoanions [PW(11)LnO(39)](4-) and four 4-Hpic ligands, which are further linked by two Ln-4-Hpic groups to form a bi-supporting structure. Then these subunits are joined together by strong hydrogen-bonding interactions between polyoxoanions and coordinated water molecules to produce a 2D supramolecular framework. All these compounds as heterogeneous Lewis acid-base catalysts show high activity and high selectivity for the cyanosilylation of different carbonyl compounds under solvent-free conditions, and can be recycled without any obvious inactivation.
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.
