What mechanical properties can be expected for materials composed of interlocked backbones has been a long-standing issue in materials science since the first reports on polycatenane and polyrotaxane in the 1970s. We successfully synthesized a three-dimensional porous metal-organic crystal composed of a [2] catenane. This porous crystal dynamically changes its geometry upon guest molecule release, uptake and exchange, and also upon temperature variation even in a low temperature range. We indented the crystal and obtained the Young’s moduli of 1.8 GPa in N,N-dimethylformamide, which is the lowest among those reported so far for porous metal-organic crystals.
