Copper cluster anions were first made via magnetron sputtering, then size selected and soft landed into a frozen matrix of 1,6-hexandithiol on highly ordered pyrolytic graphite (HOPG) maintained at 100 K. After warming up to 298 K, a combination of TPD and XPS were performed to characterize the newly deposited sample. TPD data shed light upon the adsorption and decomposition pathways of 1,6-hexanedithiol molecules on copper clusters. Based on the TPD data, two different binding motifs are proposed: the dangling motif is with one sulfur atom binding to a copper cluster, and the bidentate motif is with both sulfur atoms binding to a copper cluster. Different decomposition products were observed for each binding motif. A series of hydrogen atom titration experiments were designed to provide further evidence for the proposed decomposition mechanism. XPS measurements at varied temperatures agree well with the TPD profile by confirming the formation of dithiol ligated copper clusters through Cu–S bond formation, and the decomposition of them via C–S bond scission. How well the dithiol ligand can protect the copper clusters from being oxidized is discussed, and the ligand number per cluster is estimated.</dcterms:abstract> <dc:creator>Tang, Xin</dc:creator> <dc:language>eng</dc:language> <dc:contributor>Bowen, Kit H.</dc:contributor> <dc:contributor>Wang, Linjie</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2018-03-08T07:51:32Z</dc:date> <dc:creator>Bowen, Kit H.</dc:creator> <dc:contributor>Ganteför, Gerd</dc:contributor> <dc:creator>Bleuel, Hannes</dc:creator> </rdf:Description> </rdf:RDF>
