Metal-organic frameworks (MOFs), self-assembled from the metal ions with organic ligands, are well known for their intriguing framework topology, permanent porosity, and tunable optical properties, which have shown great promise for a good number of applications. Over the past few years, the luminescent MOFs have attracted growing attentions, especially for developing various luminescent sensors, by virtue of the excellent selectivity and high sensitivity. In this feature article, we highlight some of the recent significant progress on this active research field, and provide a comprehensive review on luminescent MOFs as sensory materials for diverse sensing applications including for metal ions, anions, small molecules and gases, nirtoaromatic and explosives, temperature, as well as other aspects.

“…Metal‐organic frameworks (MOFs) are a series of supramolecular coordination compounds, formed by metal ions or clusters and polydentate organic ligands, famous for hierarchical porosity, adjustable crystal structure, as well as large specific surface area [1] . Since their emergence, MOFs have attracted intensive attention as functional materials in hydrogen storage, [2–3] molecular recognition, [4] gas adsorption and separation, [5] selective catalyst, [6] and so on. For example, CuBTC and CuBTC‐derived composite materials are widely applied in the adsorption and removal of poluttant, [7–8] and Cu‐based organic reaction catalysts [9–11] .…”

In recent years, metal‐organic frameworks (MOFs) have been widely used in the fields of hydrogen storage, gas separation, catalysts, and so on. It is inspiring to apply MOFs in the field of electrochemistry, whereas the intrinsic low electric conductivity of MOFs limits their promising future. Herein, a new approach to improve the electronic conductivity of Cu‐MOF (CuBTC) is developed, by adopting LiTCNQ solution as the reductant to generate CuTCNQ@CuBTC (BTC=1,3,5‐benzenetricarboxylic acid; TCNQ=7,7,8,8‐tetracyanoquinodimethane) core‐shell nanoparticles with conductive CuTCNQ as the shell and non‐conductive CuBTC as the core, and the reaction conditions are optimized. Mutually validated data indicate that conductive CuTCNQ shell grows thicker with a higher temperature (60 °C) and prolonged time (24 h). With this method, the conductivity of the CuBTC material is effectively improved from 3.84×10−9 to 2.94×10−7 S cm−1.

“…Nanocrystal metal organic frameworks (NMOFs) have been projected useful in application areas such as, catalysis, nonlinear optics, electroluminescent devices, biomedical imaging and small molecules sensing (Krische and Lehn, 2000;Tanabe and Cohen, 2011;Cui et al, 2011;Della Rocca et al, 2011;Kumar et al, 2014a). NMOFs are characterized with better dispersive nature than the micsron scale MOFs and they can easily sense small molecules with no loss in their intrigue framework architectures and topologies (Wang et al, 2011a(Wang et al, , 2011b.…”

“…Availability of pendent functional groups on some NMOF structures may be utilized to tag them with biomolecules such as nucleic acid, protein, antibody and enzymes (DeKrafft et al, 2009;McKinlay et al, 2010). A Cd ion based NMOF '[Cd(atc) (H 2 O) 2 ] n ' (atc¼2-aminoterephthalic acid) has recently been proposed for the fluorescence quenching based detection of nitro aromatic compounds, including explosives and pesticides (Wang et al, 2012;Kumar et al, 2014a). Aqueous dispersibility and availability of pendent -COOH groups on this NMOF structure (Fig.…”
