“…[40] Intra-ligand based luminescence is typically observed with organic ligands that are highly conjugated, susceptible to π-stacking in the solid state. [40], [41] v. Fluorescent ligands can also be used in MOFs that are intended for biological applications, due to their ability to perform real-time measurements. [7], [42][43][44][45][46][47][48][49] For MOFs to be applicable for in vivo administration, the components of their framework should not intervene in the body's cycle, and ideally be excreted from the body.…”

Metal organic frameworks (MOFs) are extended structures composed of a network of organic ligands and metal ions or clusters connected to each other via coordination bonds. The numerous choices of organic ligands and metal coordination geometries have led to the construction of porous MOFs with various compositions, network topologies, pore sizes and shapes and they possess high surface areas and low densities. The structures of MOFs can be tailor-tuned in such a way that any desired ligand or/and metal ion can be incorporated; this has given to researchers the advantage of designing MOFs for a targeted application. Within this review, we overview recent examples of a sub-class of MOFs namely biologically derived MOFs (bio-MOFs), made of multifunctional and commercially available biologically derived ligands (bio-ligands) such as: amino acids, peptides, nucleobases and saccharides and focus on their coordination chemistry with a variety of metals. Central to this review are four tables detailing the coordination modes of bio-ligands to metals, along with a visual representation of the bio-MOF that is subsequently formed. Through the detail analysis of these structures, we highlight the structural impact of these ligands on the structure, and their contribution to the MOFs properties and applications. Finally, we showcase the potential of bio-MOFs in several research areas such as CO2 capture, separation, catalysis, drug delivery and sensing.

“…These results indicate that MOF-5 prepared by solvothermal methods yields a higher purity phase with respect to ZnO contaminants and the PL data is in agreement with the ligand-centred emission found for an analogous cubic MOF containing stilbenedicarboxylate linkers. [101] Finally, fluorescence spectroscopy was also used to monitor MOF-5 degradation by water:…”

These QD@MOF composites are an emergent class of materials and in this review we discuss current strategies for their synthesis, consider the semiconductor behaviour of MOFs themselves and present the applications of the various materials reported this far grouped by the nature of the QD component.Article contents

“…MOFs are a class of porous crystalline materials formed by the combination of transition metals or metal-containing clusters as structural nodes and organic compounds as linkers. With outstanding properties including high surface area, high pore volume, and flexibly tunable structure, MOFs were found to have a wide range of applications in gas adsorption [8,9], separation [10,11], chemical sensing devices [12], and catalysis [13]. Recently, MOFs have been discussed on its potential as a new class of photocatalysts such as MOF-5, isoreticular MOFs (IRMOF-1, IRMOF-2, IRMOF-7, IRMOF-8, IRMOF-9), MIL-53 (M = Al, Cr, Fe), UiO66 and UiO67 [14][15][16][17][18].…”

Ammonia functionalized UiO66 (UiO66-NH 2 ) in the form of thin film was synthesized by a solvothermal method combined with a dip-coating technique and determined with physicochemical characteristics by X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen physisorption measurements (BET), infrared spectroscopy (IR), thermogravimetric analysis (TGA), and ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS). Also, the obtained material was assessed on the photoactivity in the degradation of p-xylene in the gas phase. Photoreaction was carried out in the micro flow reaction system with the radiation sources of a UV lamp (λ = 365 nm, the power of 8 W) and 81 pieces of light emitting diode (LED) (λ = 400-510 nm, total power of 19.2 W). The results showed that UiO66-NH 2 was successfully prepared in the ball shape and featured by a high surface area of up to 576 m 2 /g, a band gap energy of 2.83 eV and a thermal stability of up to 673 K. Additionally, UiO66-NH 2 thin film catalyst performed an efficiency of 1.27 g/g cat in the earlier 60 minutes of the photodegradation of p-xylene. The optimal treatment conditions were established with the moisture content of 8.65 mg/L and the atmospheric oxygen with the concentration of 300 mg/L.
