Abstract

Considering the significant effect of the size of a nanocluster on its optical energy gap, we herein exploit the concept of de-assembly to render a blue-shift of the photoluminescent emission as well as an enhancement of the quantum yield (QY) of assembled M₂₅ nanoclusters. The de-assembly splits an assembled M₁₃-dimer Pt₂Ag₂₃(PPh)₁₀Cl₇ into a sole-M₁₃-kernel Pt₁Ag₁₂(dppm)₅(SPhMe₂)₂, via a Pt₁Ag₂₄(SPhMe₂)₁₈ nanocluster.
