Microgel-Stabilized Metal Nanoclusters: Size Control by Microgel Nanomorphology

Soluble crosslinked macromolecules (microgels) used as stabilizers of catalytically active metal nanoclusters allow control of the nanocluster size by simply changing the crosslinking degree of the microgel. Microgel-stabilized metal nanoclusters are easily prepared and stored in the solid state, and those of Pd (see Figure) exhibit high catalytic activity in the Heck reaction of activated aryl bromides.
