Ligand effects in photoluminescence of copper nanoclusters.

Copper nanoclusters have attracted significant interest in the field of materials science due to their high abundance, complex structure, and unique properties. However, there is a limited amount of research on the relationship between structure and properties. In this study, we synthesized and comprehensively characterized two new Cu nanoclusters, [Cu(PhSe)(PPhO)] (Cu9-1) and [Cu(CHOPhS)(PPhO)] (Cu9-2), in order to investigate the effect of ligands on photoluminescence.
