Description
Summary:The compound [(Nb 6 O 19 )@Ag 34 ( t BuC&z.tbd;C) 24 (CH 3 COO) 2 ] (Ag 34 ) was synthesized using the solvothermal method combined with volatilization. This was the first case, to the best of our knowledge, of isolating a silver cluster containing a polyoxoniobate (PONb) template. The luminescence, solution behavior and solid-state stability of Ag 34 were studied in detail. Electrospray ionization mass spectrometry indicated that Ag 34 can maintain the integrity of its skeleton in solution. Detection of temperature could be a potential application of its unique luminescent behavior. We expect this work to inspire further fabrications of PONb-templated high-nuclearity silver clusters. A polyoxoniobate-templated silver nanocluster was first obtained. The compound not only shows good chemical stability but also exhibits interesting temperature-dependent luminescent emission.
