“…The Stern–Volmer ( S‐V ) equation ( I 0 / I ) = K SV [M] + 1 is used to evaluate the quenching efficiency of Tb‐MOF by the analyte, in which K SV is the quenching constant (M –1 ), [M] is the molar concentration of the analyte, I 0 and I are the fluorescence intensities of the complexes suspension without and with the analyte , . As illustrated in Figure d, the S‐V curve linearly increases below 132 μM for MDZ and then deviates from the linearity at high concentration of MDZ.…”

A robust 4,8-connected Tb-based metal-organic framework (Tb-MOF) with paddle wheel-shaped {Tb 2 (COO) 4 } subunits extended by C 3 -symmetric 3,3Ј,3ЈЈ-[1,3,5-benzenetriyltris(carbonylimino)]trisbenzoate connector was hydrothermally synthesized, showing highly environmental stability, good dispersion and intense green emission in water system. Resulting critically from the well suppressed absorption towards the excitation energy, the Tb-MOF exhibits rapid and efficient 23 fluorescent response towards nitroimidazole antibiotics with strong quenching constants and low detection limits of 1.59 ϫ 10 4 m -1 and 2.4 μM for metronidazole as well as 1.62 ϫ 10 4 m -1 and 2.9 μM for dimetridazole. Moreover, the sensitive and selective identification of the Tb-MOF has strong anti-interference and excellent regeneration ability, which endows the promising applications of the Tb-MOF as fluorescent sensing materials.

“…Thus, MOFs demonstrate great potential applications in various fields. Owing to the decades' efforts of researchers, thousands of structures of MOFs have been discovered and applied in various fields, such as separation [31][32][33][34][35][36][37][38], adsorption [20,[39][40][41][42], optics [43][44][45][46][47][48][49][50], catalysis [19,[51][52][53][54][55][56], sensors [57][58][59][60][61][62][63], etc. However, most of these studies are based on MOFs powders.…”

In recent years, luminescent metal-organic frameworks (MOFs) as a new type of sensing material are receiving enormous attention for their superior performance in chemical sensors and biosensors [1][2]. Taking account of the excellent optical properties such as large Stokes shifts and high color purity of lanthanide MOFs (LnMOFs), a great deal of important investigations on LnMOFs have been carried out. And then, their promising abilities in detecting temperature, metal ions, oxygen, explosives and polychlorizated benzenes with high sensitivity and selectivity have also been exploited successfully [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Ratiometric luminescent sensors can provide a self-calibrated analyte concentration readout, which is unaffected by fluctuations of sensor concentration and/or instrumental parameters. However, it is noticed that a majority of related reports are limited to the detection of analyte using single emission, although ratiometric sensors based on dual-emission are more reliable and accurate than the sensors based on single emission. For ratiometric sensors, not only are two significantly different emissions necessary, but two emissions need distinctive response to the analyte. From this point of view, LnMOFs with ligand and Ln 3+ emissions are very attractive, because organic ligands and Ln 3+ ions as the luminescent centers possess completely different physical and chemical properties and they would produce different interactions with analytes. Thus, LnMOFs have been extensively applied to construct ratiometric sensors recently [3,22].Aluminium exists in soil, containers and structural materials, which may release Al 3+ due to the corrosion and/or dissolvation, inducing the increasing risk of Al 3+ absorption by the human body [23][24][25][26][27]. However, excessive Al 3+ in human body may cause damage to nucleic acids and proteins or the central nervous system [28][29][30]. Thus, it is important to detect Al 3+ with high selectivity and sensitivity, both in the environment and organisms [31,32]. As far as we are concerned, few LnMOFs display high selectivity and sensitivity for Al 3+ [33][34][35]. It is noted that Al 3+ may replace the Ln 3+ in the framework or interact with the ligands [36]. As a consequence, both ligand and Ln 3+ emissions may be interfered by Al 3+ ions. These facts impel us to realize LnMOFs ratiometric sensors for Al 3+ by the judicious choice of the organic ligand. Recently, a few works reported different fluorescence response behavior to Al 3+ ions for the emissions of the ligand and Tb 3+ ion [37,38]. In these cases, the Tb 3+ emission decreases gradually, whereas the ligand emission shows a strong enhancement as the addition of Al 3+ ions. Inspired by these cases, we aimed to synthesize LnMOFs as ratiometric luminescent sensors to detect Al 3+ ions.In this work, three Ln-MOFs, (Me 2 NH 2 )[Ln 2 L 2 (NO 3 ) 2 -(μ 3 -OH)(H 2 O)]·2H 2 O·2DMA, [Ln=Eu(1), Gd(2) and Tb (3), DMA=dimethylacetamide], were obtained based on a robust...
