“…Pioneering work within this field was performed by Li et al who demonstrated the sensitive detection of DMNB and 2,4-DNT in the vapour phase. 37 This work inspired a number of other researchers who subsequently demonstrated the successful detection of explosives, with some selectivity, using zinc, [38][39][40][41][42][43] cadmium, [44][45][46] lithium, 47 indium, 48 europium, [49][50][51][52] and terbium containing metal-organic frameworks. 53 However, the majority of the published research reports the detection of explosives using MOFs through solution-based titrations.…”

Two fluorescent metal-organic frameworks (MOFs) [Zn(dcbpy)(DMF)]·DMF and [Dy(dcbpy)(DMF) 2 (NO 3 )] (dcbpy = 2,2'-bipyridine-4,4'-dicarboxylate) were synthesised solvothermally and structurally characterised. Uniform shape and sized microcrystals of [Zn(dcbpy)(DMF)]·DMF were also produced using microwave synthesis. The frameworks give organic linkerbased fluorescence emission and demonstrate very different detection capabilities towards the explosive taggant 2,3-dimethyl-2,3-dinitrobutane (DMNB) and trinitrotoluene (TNT) derivatives; 2,4-dinitrotoulene (2,4-DNT), nitrobenzene (NB) and paranitrotoluene (p-NT). These differences are attributed to the variation in the overall framework architecture between the two MOFs. This paper reiterates the key importance of MOF porosity in sensing applications, and highlights the value of uniform microcrystals to sensitivity.

“…Up to now, a few examples in the literature demonstrate this potential application. [15][16][17][18][19][20] On the other hand, organic dyes are one of the major pollutants in water because of their long lifetimes and wide distribution. Recently, numerous methods have been employed for organic dye wastewater treatment.…”

Fluorescence Detection of Anilines and Photocatalytic Degradation of Rhodamine B by a Multifunctional Metal–Organic Framework

et al. 2014

A multifunctional transition metal CdII coordination polymer based on an amide‐inserted flexible multicarboxylate ligand, bis(3,5‐dicarboxyphenyl)terephthalamide (H4L), [CdL]·[+H2N(CH3)2] (DMF)(H2O)3 (MOF1) was synthesized by the solvothermal method. Its structure was determined by single‐crystal X‐ray diffraction analysis and it was characterized by elemental analysis, IR spectroscopy and thermogravimetric analysis. MOF1 shows selective sensitivity to detecting aniline pollutants in both aqueous media and as vapors due to its strong fluorescence emission and microporous structure. In addition, the visible‐light‐driven photocatalytic degradation of Rhodamine B (RhB) by MOF1 and polyaniline (PANI) composite material (named PANI/MOF1), which was prepared by loading PANI onto the surface of MOF1, was also studied. The results obtained illustrate that PANI/MOF1 exhibits improved photocatalytic activity over MOF1, which could be used to effectively treat wastewater containing organic dyes in the future.

“…Over the past few decades, a large number of luminescent MOF sensors for detecting cations, anions, organic small molecules, explosives and temperature have been realized and reported [6][7][8][9]. Comparing with the traditional luminescent MOFs, the characteristics of the luminescent MOF sensors are the permanent porosity, high surface areas and structural flexibility [10]. Nitrobenzene is notorious environment pollutant, which can cause serious health problems [11].…”

A new Zn(II) compound, namely {[Zn(atz) (C 2 O 4 ) 0.5 ]ÁH 2 O} n (1 Hatz = 3-amino-1,2,4-triazole), has been synthesized by the hydrothermal reactions of Zn(NO 3 ) 2 , Hatz and H 2 C 2 O 4 . Single crystal X-ray structure analysis reveals that compound 1 features a 3D porous pillar-layer structure with 6-connected pcu topology. The free water molecules are filled in the 1D channels. Thermal analysis reveals that it can be stable up to 347°C. Luminescence investigation for 1 reveals that it can be used as a good candidate for sensing of nitrobenzene.
