Sub-nanometer Cu(i) clusters: coordination-modulated (Se vs. S) atom-packing mode and emission

摘要

Herein, the ligands' effect in Cu(i) clusters was initially explored. The results demonstrate that the Se atom possesses more coordination modes with Cu (mu(2), mu(3), mu(4), mu(6)) than S, which significantly modulates the atom-packing mode of Cu(i) clusters. Importantly, this also endows these clusters with different temperature-dependent luminescent behaviours.
