报告摘要：
While metal-organic frameworks (MOFs) are predominantly studied for their crystalline, microporous structures, recent discoveries regarding their melting behavior have unlocked a new class of materials: MOF-derived glasses. This presentation highlights recent advances in the field, focusing on the synthesis and exceptional properties of MOF glass nanocomposites. By dispersing a crystalline MIL-53 phase within a ZIF-62 glass matrix, a composite material is formed where the distinct phases interact at their interfaces, resulting in significantly enhanced mechanical stability. Crucially, this composite stabilizes the high-temperature, open-pore phase of MIL-53 at room temperature, thereby leading to a dramatic increase in CO₂ adsorption capacity compared to its pure crystalline counterpart. Furthermore, we demonstrate that the inherent chemical tunability of MOFs is retained in the glassy state. Through ligand functionalization, the melting behavior, mechanical properties, and microporosity of both crystals and their melt-quenched glasses can be precisely tailored, providing deeper insight into melting mechanisms governed by the dynamics of metal-organic linkages. Beyond gas adsorption, these versatile glass composites show great promise in applications such as photocatalysis, where functionality can be designed into a stable glass matrix, as well as in membrane separation, which benefits from their tunable porosity and robustness. These findings underscore the broad potential of MOF glasses, paving the way for innovative applications in energy, environmental, and chemical processing technologies.
