Abstract

Structural transitions of host systems in response to guest binding dominate many chemical processes. We re-port an unprecedented type of structural flexibility within a meta-rigid material, MFM-520, which exhibits a reversible “peri-odic-to-aperiodic” structural transition, resulting from a drastic distortion of a [ZnO4N] node controlled by the specific host-guest interactions. The aperiodic crystal structure of MFM-520 has no three-dimensional (3D) lattice periodicity but shows translational symmetry in higher dimensional (3+2)D space. We have visualised directly the aperiodic state which is induced by incommensurate modulation of the periodic framework of MFM-520·H2O upon dehydration to give MFM-520. Filling of MFM-520 with CO2 and SO2 reveals that while CO2 has a minimal structural influence, SO2 can further modulate the structure incommensurately. MFM-520 shows exceptional selectivity for SO2 under flue-gas-desulfurisation conditions, and the facile release of captured SO2 from MFM-520 enabled the conversion to valuable sulfonamide products. MFM-520 can thus be used as a highly efficient capture and delivery system for SO2.
