On the other hand, the disassembly of the interlocked architecture through the breakdown of the mechanical bond can activate properties which are masked in the parent compound. Herein, we present the development of stimuli\u2010responsive Cu\n                    <jats:sup>I<\/jats:sup>\n                    \u2010complexed [2]catenanes as OFF\/ON catalysts for the copper\u2010catalyzed alkyne\u2010azide cycloaddition (CuAAC) reaction. The encapsulation of the Cu\n                    <jats:sup>I<\/jats:sup>\n                    ion inside the [2]catenanes inhibits its ability to catalyze the formation of triazoles. In contrast, the controlled opening of the two macrocycles induces the breaking of the mechanical bond, thereby restoring the catalytic activity of the Cu\n                    <jats:sup>I<\/jats:sup>\n                    ion for the CuAAC reaction.
