The Alloying-Induced Electrical Conductivity Of Metal-Chalcogenolate Nanowires

Alloying is one of the most effective strategies to change the properties of inorganic-organic hybrid materials, but there are few reports of the alloying of one-dimensional nanowires with precise atomic structure due to the difficulties in obtaining the single crystals of nanowires themselves. Herein, we describe the synthesis and characterization of an alloyed one-dimensional Ag-Cu nanowire [Ag2.5Cu1.5(S-Adm)(4)](n). Compared with the unalloyed [Ag-4(S-Adm)(4)](n), our novel alloyed nanowire exhibits good conductivity, and its resistivity (as a powder) was determined to be 107 omega m by impedance analysis-consistent with that of a semiconductor. Accordingly, based on these properties combined with its excellent thermal stability and high-yielding, gram-scale synthesis, [Ag2.5Cu1.5(S-Adm)(4)](n) is proposed for electronic-device applications.
