摘要：

We have developed a rotaxane-based mechanophore system that is capable of breaking a mechanical bond and releasing small molecules via force-triggered rotaxane disassembly. In this design, a cyclobutane mechanophore was fused to the ring component of a rotaxane, constructed through a template-mediated synthesis in high yields. Upon opening the ring component, the rotaxane disassembled to release the axle molecule. We successfully demonstrated and quantified the force-triggered release of the axle molecule in both solution and solid-state samples. [GRAPHICS] .
