Copper cluster macromolecules are nanoscale materials comprised of a copper core or frame enclosed by a mantle of stabilizing ligands. Its exploration offers advancement in various fields from electronics and energy to medicine. Copper clusters have potential to further progress in fundamental chemistry as catalysts, reducing agents, corrosion inhibitors, and petroleum sweeteners, for instance. Nanoscale materials were synthesized from copper salts using borohydride reducing agents, and a protecting ligands to optimize their composition, structure, size, and reactivity. Results demonstrated glutathione is an excellent stabilizing ligand for the macromolecule. When prepared in anaerobic alkaline conditions, the nanoparticle is air stable for months at a time, and it shows high cohesion as judged by its melting point (&gt;250°C). Polyacrylamide gel electrophoresis shows monodispersity at less than 3nm diameter, and surprisingly, UV-Vis spectrometry demonstrates the material absorbs strongly in the near infrared (&gt;1100nm).
