“…Many examples of silicas and zeolites with ordered cubic and hexagonal mesoporosity 172 and hybrid periodic mesoporous 15 organosilicas (PMOs) 173 have already been successfully prepared in this way, but their functionality could be further enhanced if similar mesoporous phases could be prepared from extended coordination networks, by incorporating both transition metal properties and organic functionality and flexibility. 174 Further, 20 and similar to the MOF@polymer systems outlined previously 31,103 , the resulting hierarchical porosity will combine unhindered mass transport through the mesopores and tunable micropore functionality and selectivity.…”

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.

“…[5][6][7][8] Mesoporous silicas have emerged as a new class of promising candidates for enzyme immobilization owing to their large surface area, ordered porous structure, narrow pore-size distribution, facile functionalization, and chemical and mechanical stability. [9][10][11] However, enzymes that are accommodated inside mesoporous silicas often exhibit lower activity compared with the native enzymes. The altered microenvironment around the immobilized enzymes is regarded as one of the main reasons for this decreased activity.…”

Macromolecular crowding is an ubiquitous phenomenon in living cells that significantly affects the function of enzymes in vivo. However, this effect has not been paid much attention in the research of the immobilization of enzymes onto mesoporous silica. Herein, we report the combined effects of macromolecular crowding and surface hydrophobicity on the performance of an immobilized enzyme by accommodating lipase molecules into a series of mesoporous silicas with different amounts of inert poly(methacrylate) (PMA) covalently anchored inside the nanopores. The incorporation of the PMA polymer into the nanopores of mesoporous silica enables the fabrication of a crowded and hydrophobic microenvironment for the immobilized enzyme and the variation in polymer content facilitates an adjustment of the degree of crowding and surface properties of this environment. Based on this system, the catalytic features of immobilized lipase were investigated as a function of polymer content in nanopores and the results indicated that the catalytic efficiency, thermostability, and reusability of immobilized lipase could all be improved by taking advantage of the macromolecular crowding effect and surface hydrophobicity. These findings provide insight into the possible functions of the macromolecular crowding effect, which should be considered and integrated into the fabrication of suitable mesoporous silicas to improve enzyme immobilization.
