Abstract:
An organic-inorganic hybridized polyoxotungstate which contains two kinds of covalently linked tungstate clusters in its polyanion has been obtained. The three clusters are connected by glutamic acid molecules and europium atoms through Eu-O-C bonds. The cluster in the middle position is a tetramer. Two of the same clusters at two sides are dimers that are functionalized by glutamic acid molecules. The solid-state luminescence of this compound exhibited the characteristic emission of Eu3+ centers with a lifetime of 232 μs.
