Passivation of the metal surface by dendrons bearing a focal 4‐pyridone functionality (the second‐generation dendron is shown; C: gray, N: blue, O: red) allows controlled nucleation and growth of gold nanoclusters. The particle size is a direct function of the generation number of the dendritic ligands, with higher generation dendron producing larger particles.
