“…The tunable pore sizes and functionalities of the nm sized pores of MOFs are clearly of 95 interest for this application, and a few studies reporting separation using MOFs as chromatographic stationary phases (CSPs) are known 85 , including in single MOF crystals. 86 In order to improve their separation capability, and monodispersity and packing density in chromatography columns however, the preparation of MOF-composite CSPs is emerging as a powerful strategy. Ameloot et al have prepared MOF-silica composite particles as 10 stationary phases in liquid chromatography by first impregnating commercial unmodified Nucleosil 100-3 (100 Å pore size, 3 µm particles) silica with a HKUST-1 seeding solution, whereby MOF deposition is induced by solvent evaporation.…”

Metal–organic framework growth at functional interfaces: thin films and composites for diverse applications

2012

5Porous metal-organic frameworks (MOFs) are highly ordered crystalline materials prepared by the selfassembly of metal ions with organic linkers to yield low density network structures of diverse topology. MOFs have attracted considerable attention over the last decade due to their facile preparation, tunable pore metrics and the ease of functionalisation of their internal surfaces, such that designer frameworks with exceptional properties for application in gas-storage, separation of small molecules, heterogeneous 10 catalysis and drug delivery are becoming commonplace. For any material to find practical utility however there is a need for processing and formulation into application-specific configurations. One way to do this is to prepare composite materials where the MOF is supported on a planar substrate or some other shaped body through interaction with functional groups at the support interface. This is a rapidly developing research area, and this review provides an overview of the diverse MOF composite materials prepared up 15 to now, organised by interface type. The importance of the interface is explored within each section and while the overall emphasis is on applications of the composites, coatings and MOF-based devices, the most widely-used and successful synthetic strategies for composite formation are also presented.

“…Although ion-exchange of small or bulky guest species into charged frameworks has been observed [6][7][8][9][10]31 , most of the studies were focused on the capture of specific metal ions 6,7 or the enhancement of gas-sorption capability 8 . There are also examples of liquid chromatography for organic dyes using Zn MOFs with neutral framework [33][34][35] , which are less likely to involve ion-exchange.…”

Selective anion exchange with nanogated isoreticular positive metal-organic frameworks

et al. 2013

Crystalline porous materials, especially inorganic porous solids such as zeolites, usually have negative frameworks with extra-framework mobile cations and are widely used for cation exchange. It is highly desirable to develop new materials with positive frameworks for selective anion exchange and separation or storage and delivery. Recent advances in metalorganic framework synthesis have created new opportunities in this direction. Here we report the synthesis of a series of positive indium metal-organic frameworks and their utilization as a platform for the anion exchange-based separation process. This process is capable of size-or charge-selective ion-exchange of organic dyes and may form the basis for size-selective ion chromatography. Ion-exchange dynamics of a series of organic dyes and their selective encapsulation and release are also studied, highlighting the advantages of metal-organic framework compositions for designing host materials tailored for applications in anion separation and purification.
