A stepwise bulk-to-cluster-to-particle transformation toward the efficient synthesis of alkynyl-protected silver nanoclusters†
Abstract
We report herein the efficient synthesis of alkynyl-protected silver nanoclusters in terms of macrocycle-assisted bulk-to-cluster-to-nanoparticle transformation. Different substituted phenylacetylide ligands are applied to stabilize the silver nanoclusters by metal–carbon bonds and meanwhile determine the size of silver nanoclusters.
