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.
