Mechanical bonds are known to efficiently absorb mechanical energy at low forces, but their behavior high forces is unknown. Here we investigate the impact of a bond on rate activation Diels-Alder mechanophore. Using combination experimental and computational techniques, found that retro-Diels-Alder reaction under tension decreased when mechanophore embedded in axle rotaxane due presence competing high-stress region junction between macrocycle axle.
