Mass Spectrometry Guided Surface Modification of the Tellurate Ion Templated 36-Nucleus Silver Alkynl Nanocluster

Under the guidance of the ESI-MS result of our former reported cluster [TeO6@Ag36(C≡CtBu)18(tfa)12] (1, tfa = trifluoroacetate), we fabricate a new 36-nucleus silver-alkynyl cluster substituted by four pentafluorobenzoates, named [TeO6@Ag36(C≡CtBu)18(tfa)8(F5PhCO2)4] (2). After four shell ligands substitution, cluster 2 emits green yellow light in the solid state, remarkablely changed with the near-infrared luminescence emission of cluster 1.
