“…For example, Dincă et al . reported a novel tetrathiofulvalene (TTF) tetrabenzoate based ssp framework, MIT‐25, in which three conjugated electron‐rich TTF cores define an organic SBU through supramolecular π‐π interactions . However, the targeted introduction of π‐π interactions with considerable strength could be a challenge in the aspect of ligand design, and thus relatively limited investigation has been performed.…”

Summary of main observation and conclusion A synergistically directed assembly approach to distinctive metal‐organic frameworks utilizing both donor‐acceptor (D‐A) interaction from aromatic systems and coordination interactions is presented. Based on such an approach, the coronene‐tpt (tpt = 2,4,6‐tri(4‐pyridyl)‐1,3,5‐triazine) stacks based coronene‐MOF‐1—4 have been successfully fabricated. Their structural discrepancies with coronene‐ absent control products, 1′—4′, illustrate clearly the significance of coronene‐tpt based D‐A interactions in these architectures. All these coronene‐MOFs contain varied coronene‐tpt stacks as organic secondary building blocks (SBUs), which are closely interrelated with the coordination based framework structures. Moreover, porous coronene‐MOF‐1 and ‐2 exhibit high physicochemical stability and significant light hydrocarbons storage and separation performances.

“…To date, the synthetic strategies toward this aim include: i) forming mixed matrix membranes by doping pre‐synthesized MOFs; ii) forming metal–organic gels through sol–gel processes; and iii) employing 2D/3D structured supports for loading MOF particles . However, these approaches lack control over the organization of the MOFs inside the support, resulting in severe MOF aggregation, low MOF contents (usually <30 %), ill‐defined hierarchical porosity, and poor formability of the support.…”

Processing metal–organic frameworks (MOFs) into hierarchical macroscopic materials can greatly extend their practical applications. However, current strategies suffer from severe aggregation of MOFs and limited tuning of the hierarchical porous network. Now, a strategy is presented that can simultaneously tune the MOF loading, composition, spatial distribution, and confinement within various bio‐originated macroscopic supports, as well as control the accessibility, robustness, and formability of the support itself. This method enables the good dispersion of individual MOF nanoparticles on a spiderweb‐like network within each macrovoid even at high loadings (up to 86 wt %), ensuring the foam pores are highly accessible for excellent adsorption and catalytic capacity. Additionally, this approach allows the direct pre‐incorporation of other functional components into the framework. This strategy provides precise control over the properties of both the hierarchical support and MOF.

“…Metal-organic frameworks (MOFS) are kinds of material formed via self-assembly of organic compounds and metals, [69] belonging to the family of coordination polymers (CPs). This kind of materials not only has ultra-high specific surface area, [70][71][72][73] rich topological structure, [74][75][76][77] but high tailorability and designability. They have been extensively studied in the fields of gas adsorption, separation and storage, [78][79][80] fluorescence, [81][82][83] magnetism, [84][85][86][87] and biopharmaceuticals.…”

Residual pollutants in the water treatment process restrict the advanced treatment and purification of wastewater, because most of them have stable structures, and some are not easily to be enriched. Photocatalytic oxidation technology can directly use solar energy to drive a series of chemical reactions, which has advantages such as low energy consumption, mild reaction conditions and rarely secondary pollution. It is an effective way to solve the organic pollution problem in wastewater treatment. The key to this process is to find and design efficient photocatalysts. The current photocatalytic materials mainly include inorganic semiconductors and metal organic frameworks (MOFs). They have been studied for pollutants degradation, hydrogen evolution, CO2 reduction, and organic transformation. But, most of these catalysts have not been used in real application. In this paper, recent research advances in MOFs photocatalysts and the key factors affecting their photocatalytic efficiency were critically reviewed. It is believed that the pursuit of more efficient photocatalyst needs to be considered from the adsorption‐photocatalytic mechanism, redox‐free radical mechanism, valence‐level regulation mechanism and energy transfer mechanism of photocatalysis. It is very necessary to research and develop nanoscale and quantum level mixed valence MOFs photocatalysts, which are constructed by strong electron‐donating groups.
