Melt-quenched metal-organic framework (MOF) glasses have gained significant interest as the first new category of glass reported in 50 years. In this work, an amine-functionalized zeolitic imidazolate (ZIF), denoted ZIF-UC-6, was prepared and demonstrated to undergo both melting formation. The presence amine group resulted a lower temperature compared other ZIFs, while also allowing material properties be tuned by post-synthetic modification (PSM). As prototypical example, ZIF surface...

We present Generative Toolkit for Scientific Discovery (GT4SD). This extensible open-source library enables scientists, developers, and researchers train use state-of-the-art focused on organic design.

The interface within a composite is critically important for the chemical and physical properties of these materials. However, experimental structural studies interfacial regions metal-organic framework (MOF) composites are extremely challenging. Here, we provide first example new MOF family, i.e., using an inorganic glass matrix host in place commonly used organic polymers. Crucially, also decipher atom-atom interactions at interface. In particular, dispersed zeolitic imidazolate (ZIF-8)...
Hybrid organic–inorganic materials represent a fascinating class of compounds that combine the unique properties both organic and inorganic materials. This review provides an overview two classes hybrid materials: metal–organic frameworks perovskites, with their structures, applications, responses to external stimuli discussed. These hybrids leverage versatility molecules, for example, flexibility functionality, alongside robustness stability components through coordination between...

We explored photocatalytic performance materials, examined materials' band gap using UV-Vis reflectance spectroscopy.
The development of metal-organic framework (MOF) crystal-glass composites (CGCs) has been hindered by the scarcity MOF glass matrices with low transition temperatures (Tgs). Here, we investigate a CGC consisting low-Tg glass, (agZIF-UC-7) and UiO-66. Powder X-ray diffraction stability tests in phosphate buffer saline solution showed UiO-66 was stabilised matrix. Additionally, composite exhibited enhanced dye uptake gas adsorption relative to agZIF-UC-7.
Abstract Separating gases using membranes is appealing due to their efficiency and low energy requirements. MOF glasses combine the advantages MOFs with processability of glasses, making them excellent materials for next‐generation membranes.

The structural instability in a humid environment of the majority metal–organic frameworks (MOFs) is challenging obstacle for their industrial-scale development. Recently, two water-resistant MOFs have been synthetized, STAM-1 and STAM-17-OEt. They both contain copper paddle wheels, like well-known water-sensitive HKUST-1, but different organic linkers. crystal lattice undergoes phase transition upon interaction with water molecules.
