Large MOFs: synthesis strategies and applications where size matters

Abstract

The large (usually more than 100 μm) single crystal 3D and especially 2D metal-organic frameworks (MOFs) are a class of porous materials having a great potential to be applied in...

Hierarchical Assembly of a Micro‐ and Macroporous Hydrogen‐Bonded Organic Framework with Tailored Single‐Crystal Size

“…Interestingly, this could have a diverse range of implications in different applications. [28] In this respect, as proof of concept, we explored the use of the hierarchical porosity nature of MM-TPY for the dual, sequential, and selective co-recognition of molecular species and solid microparticles (Figure 5). Although the selective adsorption of molecular species in solution is well studied, the selective recognition of solids is less explored and very challenging.…”

Imparting Functionality and Enhanced Surface Area to a 2D Electrically Conductive MOF via Macrocyclic Linker

“…Beyond designing a new ligand motif, precise control over particle size enables tuning the properties of materials, such as surface area, adsorption/desorption kinetics, and diffusion rates . For instance, smaller particles can lead to large surface area, high ratio of exposed active sites, and rapid diffusion of guest molecules into internal pores, which are key parameters for energy-related applications and sensing.…”

Terbium(iii)-based coordination polymer with millimeter-size single crystals and high selectivity and sensitivity for folic acid

“…Among them, complexes with large-size crystals are not only conducive to the accurate determination and analysis of structures but also provide a potential possibility for use in single crystal devices in practical applications. 25,26 Therefore, large single crystals are considered to be a convenient platform to study the intrinsic properties of a complex and to assess the "structure-property" interconnection. Despite the increasing interest in large-size complex single crystals, the strategies for obtaining such materials have not been fully studied, resulting in a relatively slow development in this field, because the influence of the external environment and internal factors on the crystal formation process is extremely complex (such as the reaction temperature, time, pH, cooling rate, reactant concentration, ratio, etc.).…”
