Abstract: The effect of substituting linkers with electron-donating moieties for part of the conventional ones on the melting and glass transition behaviours of ZIF-62 was investigated by calorimetry and X-ray diffraction.

Abstract: The node-and-linker structure of metal-organic frameworks could enable detailed structural studies of molecular glasses quenched from melts. Zinc-based zeolitic imidazole frameworks exhibit a high propensity for glass formation at conventional cooling rates. Madsen et al. used ultrahigh magnetic fields (19.5 and 35.2 tesla) to perform zinc-67 nuclear magnetic resonance of solid s les with magic-angle spinning on three s les with different ratios of imidazole and benzimidazole linkers. The structural disorder of the tetrahedral ligand environment around zinc nodes was higher in the glassy states than in the parent crystals. Science , this issue p. 1473

Abstract: The mixed metallic node effect is discovered in bimetallic zeolitic imidazolate frameworks ( i.e. , Co,Zn-ZIF-62) through a combination of experimental and modelling studies.

Abstract: Metal coordination compound (MCC) glasses [e.g., metal‐organic framework (MOF) glass, coordination polymer glass, and metal inorganic‐organic complex (MIOC) glass] are emerging members of the hybrid glass family. So far, a limited number of crystalline MCCs can be converted into glasses by melt‐quenching. Here, we report a universal wet‐chemistry method, by which the super‐sized supramolecular MIOC glasses can be synthesized from non‐meltable MOFs. Alcohol and acid were used as agents to inhibit crystallization. The MIOC glasses demonstrate unique features including high transparency, shaping capability, and anisotropic network. Directional photoluminescence with a large polarization ratio (≈47 %) was observed from s les doped with organic dyes. This crystallization‐suppressing approach enables fabrication of super‐sized MCC glasses, which cannot be achieved by conventional vitrification methods, and thus allows for exploring new MCC glasses possessing photonic functionalities.
