The present work describes the spectroscopic and photodynamics of two different Zr mixed-linkers MOFs (Zr-NDC/Tz and Zr-NDC/CN) and their interaction with nitroaromatics. Both MOFs exhibit comparable spectroscopic behaviours, with a broad emission band mainly due to the naphthalene excimers within their three-dimensional structure. Flash photolysis experiments show a slow radiative electron-hol...

Metal organic frameworks (MOFs), an emerging class of crystalline nanoporous materials, have recently caught attention for their unique properties such as high surface area, large pore volume, high uniform and permanent porosity, and ease of chemical tenability to introduce additional physical, chemical, or electrical properties. MOFs constructed from inorganic and organic pieces: metal ions an...

Metal–organic frameworks (MOFs) are newly emerging porous materials. Owing to their large surface area and tunable pore size and geometry, they have been studied for applications in gas storage and separation, especially in hydrogen and methane storage and carbon dioxide capture. It has been well established that the high-pressure gravimetric hydrogen-adsorption capacity of an MOF is directly p...

This paper reports an enhancement in fluorescence detection via the formation of fluidic microlens in micro-optical fluidic system (MOFS). The fluidic microlens is formed by three laminar flows in the expansion chamber. By changing the flow rate of each flow, the shape and focal length of the fluidic lens will be changed. Therefore, the fluidic microlens provides a wide range of tunability to e...

Recent progress in the synthesis and characterization of metal-organic frameworks (MOFs) has opened the door to an increasing number of possible catalytic applications. The great versatility of MOFs creates a large chemical space, whose thorough experimental examination becomes practically impossible. Therefore, computational modeling is a key tool to support, rationalize, and guide experimenta...

A series of zirconium-based, metal-organic frameworks (MOFs) were tested for their ability to adsorb and remove selenate and selenite anions from aqueous solutions. MOFs were tested for adsorption capacity and uptake time at different concentrations. NU-1000 was shown to have the highest adsorption capacity, and fastest uptake rates for both selenate and selenite, of all zirconium-based MOFs st...

Metal-organic frameworks (MOFs) are chemical systems comprising organic molecules coordinated to metal ions or clusters to form one-, two-, or three-dimensional structural arrangement (Figure 1). The use of lanthanide (Ln) ions results in a specific class of Ln-MOFs possessing unique physico-chemical properties owing to a large atomic magnetic moment, strong spin-orbital coupling, high coordina...

Amongst many strategies for renewable energy conversion, light-driven water splitting to produce clean H2 represents a promising approach and has attracted increasing attention in recent years. Owing to the multi-electron/multi-proton transfer nature of water splitting, low-cost and competent catalysts are needed. Along the rapid development of metal–organic frameworks (MOFs) during the last tw...

We report the study of the resistance of archetypal MOFs (MILs, HKUST-1, UiO-66, and ZIF-8) under gamma irradiation. The different porous solids were irradiated with doses up to 1.75 MGy. All the MOFs constructed with transition metals (Cu2+, Zn2+, Zr4+) exhibit an evident destruction of the framework, whereas the compounds constructed with aluminium remain intact.
