“…Metal coordination compound (MCC) glasses are the fourth known family of melt-quenched glasses, besides the other inorganic, organic and metallic families. [1,2] They possess a network structure, in which metal nodes are coordinated to organic moieties. This new family of glass is considered to be a promising material for various applications, e.g., gas separation, energy storage and photonics.…”

“…[28,29] Similar to MOFs and CPs, MIOCs suffer from sublimation during melting, [32,33] while few examples of MIOCs could be transformed into glasses by melting-quenching when the decomposition of organic moieties during melting at high temperatures was minimized. [2,13,30] Furthermore, amorphous MCCs can be obtained by mechanical milling methods. [1,20,28] Generally, the fabrication of bulk MCC glasses is difficult and hence restricts the practical applications of MCCs.…”

“…However, it was reported that the 2D CPs lose their structural periodicity after glass formation as the occurrence of a high degree of distortion around metal ions during melting [28, 29] . Similar to MOFs and CPs, MIOCs suffer from sublimation during melting, [32, 33] while few examples of MIOCs could be transformed into glasses by melting‐quenching when the decomposition of organic moieties during melting at high temperatures was minimized [2, 13, 30] . Furthermore, amorphous MCCs can be obtained by mechanical milling methods [1, 20, 28] .…”

“…Using this approach, we synthesize a novel hydrogen-bonded MIOC glass (i.e., Zn(NO 3 ) 2 (Hbim) 2 , Hbim = protonated benzimidazole) [35] through suppressing the crystallization of non-meltable 2D zeolitic-imidazolate framework-7-III (ZIF-7-III) [24] (i.e., Zn 2 (bim) 4 , bim = benzimidazole; ZIFs are a sub-set of MOFs [36] ) in a solution, rather than the commonly used direct melt-quenching of MCCs. [2] It is expected that molecules including ethanol and nitric acid insert into the ZIF network, coordinate with the metal centers, and distort the framework by interrupting its structural periodicity, thereby transforming the framework into a hydrogen-bonded MIOC network. The addition of alcohol and acid induces significant geometric deformation of the ZIF, and finally results in a new MIOC glass with a supramolecular network.…”

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 samples 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.

Glassy states of network‐forming coordination polymers (CPs) and metal‐organic frameworks (MOFs) represent a novel category of amorphous materials. Recent years have seen substantial progress in expanding the compound library and advancing the structural design of CP/MOF glasses. This review examines the current status and future potential of multi‐scale hierarchical CP/MOF glass materials, covering synthesis, shape adaptability, and synergistic materials. Extensive experimental and theoretical investigations of structure‐property relationships have shed light on their diverse utility, spanning areas such as permanent porosity and gas permeability, ionic and electronic conductivity, optics, catalysis, and battery technology. Additionally, the inherent properties of these glasses, coupled with their phase transformation capability, enable a range of morphological architectures. Current challenges are also addressed and offer insights into future research, with the goal of bringing CP/MOF glasses to the industry.
