Titolo: Responsive Porous Frameworks: Serendipity or Rational Design?
Abstract. Porous materials play a key role for the capture of gases such as CO2, air filtration for clean air, isotope separation and the development of novel catalysts. Responsivity of MOFs towards gas and liquid phase stimuli presents tremendous chances for applications in gas storage, separation, sensing and actuation. Despite emerging applications, the rationalization of flexibility phenomena is still at an early stage. In recent years in silico methodologies have made great progress to model the entire energetic landscape of complex host guest interactions and framework dynamics. However, experimental observations such as finite size effects, activation barriers and sample history require an interplay of experimental and analytical techniques combined with simulation. We emphasize the importance of MOF model materials to shine light on the complex interplay of materials descriptors (structure, disorder, finite size, morphology, history etc.) and their analyses using dedicated in situ characterization tools (XRD, NMR, EPR, XAS etc.) for advancing the understanding of stimuli responsive porous framework materials in future. A historical perspective will be provided for specific examples (DUT-8, DUT-49) to highlight the role of the curious and critical observer as an essential prerequisite to discover new phenomena. In summary, the presentation provides insights into tailor made porous materials and highlight their functionality with respect to gas storage, separation, ion storage and applications in batteries.
