Here, we propose the combination of glassy or crystalline metal‐organic frameworks (MOFs) with inorganic glasses to create novel hybrid composites and blends.The motivation behind this new composite approach is to improve the processability issues and mechanical performance of MOFs, whilst maintaining their ubiquitous properties. Herein, the precepts of successful composite formation and pairing of MOF and glass MOFs with inorganic glasses are presented. Focus is also given to the synthetic routes to such materials and the challenges anticipated in both their production and characterisation. Depending on their chemical nature, materials are classified as crystalline MOF‐glass composites and blends. Additionally, the potential properties and applications of these two classes of materials are considered, the key aim being the retention of beneficial properties of both components, whilst circumventing their respective drawbacks.

The chemistries that can be incorporated within melt-quenched zeolitic imidazolate framework (ZIF) glasses are currently limited. Here we describe the preparation of a previously unknown purine-containing ZIF which we name...

Here we present efficient and scalable mechanochemical formation of hybrid organic-inorganic perovskites of the form [TPrA][M(dca)3] (M = Mn2+, Co2+) and the subsequent formation of their bulk melt-quenched glass samples....

The formation of hybrid materials through the combination of the chemically versatile, functional metal‐organic framework (MOF) family is proposed, with ubiquitous, low cost and durable inorganic glasses. The blends and composites hence created may serve to minimise, and eventually solve cost, durability and processability issues of MOFs, whilst retaining their valuable properties.

The interface within a composite is critically important for the chemical and physical properties of these materials. However, experimental structural studies of the interfacial regions within metal-organic framework (MOF) composites are extremely challenging. Here, we provide the first example of a new MOF composite family, i.e. using an inorganic glass matrix host in place of the commonly used organic polymers. Crucially, we also decipher atom-atom interactions at the interface. Specifically, we dispersed ZIF-8 within a phosphate glass matrix, and identified interactions at the interface using several different analysis methods of pair distribution function (PDF) and multinuclear multidimensional magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy. These demonstrated glass-ZIF atom-atom correlations. Additionally, carbon dioxide uptake and stability tests were also performed to check the increment of the surface area and the stability and durability of the material in different media. This opens up the possibility to create new composites including the intrinsic chemical properties of the constituent MOFs and inorganic glasses.
