In this paper, stress\u2010sensing materials, triggered by a mechanoresponsive catalytic system based on latent copper(I)bis(<jats:italic>N<\/jats:italic>\u2010heterocyclic carbene) mechanophores, are reported, which can be activated by compression force to trigger a fluorogenic copper(I)\u2010catalyzed alkyne\/azide \u201cclick\u201d cycloaddition reaction, activating a fluorescent dye useful for stress\u2010sensing applications in bulk polymeric materials. The focus is placed on the polymeric architecture, which is responsible for an efficient stress transmission, revealing the greatest activation for network\u2010based mechanocatalysts, observing \u201cclick\u201d conversions up to 44%, while chain\u2010extended and linear mechanocatalysts activate either in a less efficient manner or are not completely latent in the initial state.
