The capability to easily synthesize a broad spectrum of metal clusters (MCs) with their size controllable in a sub-nanometer scale presents an enticing prospect for exploring nanosize-dependent properties. This contribution reports an innovative design of a polymeric capping agent from a polytriazolium poly(ionic liquid) (PIL) in a vesicular form in solution that allows for crafting a variety of MCs including transition metals, noble metals, and their bimetallic alloy with precisely controlled sizes (~ 1 nm). The ultrastrong stabilization power is result of an unusual synergy between the conventional binding sites in the heterocyclic cations in PIL, and an in-situ generated polycarbene structure that are induced simultaneously to the reduction reaction.
