Mechanochemically Triggered “Click” Catalyst.

Triggering CuAAC reaction by mechanical force enables site- and stress-specific “click” reactions. We introduce the design and realization of a homogeneous Cu catalyst able to activate through mechanical force when attached to suitable polymer chains. Based on an N-heterocyclic copper(I) carbene with attached polymeric chains of different flexibility, the force is transmitted to the central catalyst, thereby activating a CuAAC in solution and in the solid state.
