“…The bond lengths of Zn-O (1.932-2.060 Å) and Zn-N (1.932-2.060 Å) both are in the normal ranges, respectively. [55][56][57][58][59][60] The two L1 3− ligands in each asymmetric unit both adopt the μ 3 -η 0 : η 1 : η 1 : η 0 : η 1 : η 0 coordination mode (mode III, Scheme S1 †). The Zn1 ions are connected to L1 3− anions by O1 and O5 to form zigzag one-dimensional chains (Fig.…”

“…For example, Jia et al, designed an MOF-modified gel (Zn2@ZIF-8@SA) {[Zn(tbia)·H 2 O]·H 2 O}n(Zn 2 ) that was portable, had a good stability, compression resilience, and was toxicologically innocuous, by a simple polymerization strategy, with which to detect and remove pesticides from the environment. Indeed, the Zn2@ZIF-8@SA was stable in H 2 O, evaluated up to 30 days, and in harsher environments including various organic solvents (i.e., N,N-dimethylformamide (DMF), acetonitrile (CH 3 CN), ethanol (EtOH)) up to 7 days [ 161 ]. Lu et al, prepared CDs@Fe/Zr-MOF based on a smartphone-assisted dual-color ratiometric fluorescence smart gel label-based visual sensing platform.…”

Metal–organic frameworks (MOFs) have excellent applicability in several fields and have significant structural advantages, due to their open pore structure, high porosity, large specific surface area, and easily modifiable and functionalized porous surface. In addition, a variety of luminescent guest (LG) species can be encapsulated in the pores of MOFs, giving MOFs a broader luminescent capability. The applications of a variety of LG@MOF sensors, constructed by doping MOFs with LGs such as lanthanide ions, carbon quantum dots, luminescent complexes, organic dyes, and metal nanoclusters, for fluorescence detection of various target analyses such as ions, biomarkers, pesticides, and preservatives are systematically introduced in this review. The development of these sensors for portable visual fluorescence sensing applications is then covered. Finally, the challenges that these sectors currently face, as well as the potential for future growth, are briefly discussed.

“…However, some recent studies have implicated Glyph as potentially hazardous and may be responsible for metabolic disorders, reproductive and immune system problems, DNA or kidney damage, endocrine disturbance, and even death. − Therefore, there is an urgent need to develop high-efficiency sensing methods and materials for the detection of Glyph. Among different reported methods, fluorescence sensing technology has gained increasing popularity in scientific research due to its advantages of low cost, simple operation, fast response, high sensitivity, and so on, which has resulted in vigorous growth of fluorescence sensing materials in the past decade. − …”

Owing to the large-scale consumption of pesticides and their potential threats to the environment and human health, the development of sensing materials for pesticides has attracted considerable attention in recent years. In this work, a novel Cd(II)-based coordination polymer (CP) with the formula [Cd(H 2 O) 2 (L)]•DMF (Cd-1, DMF = N,N-dimethylformamide, H 2 L = 4,4′-[(2,5-dimethoxy-1,4-phenylene)di-2,1-ethenediyl]bis-benzoic acid) was synthesized under solvothermal conditions. Structural analysis revealed that coordination between central Cd 2+ cations and the ligand L 2− formed two-dimensional (2D) networks, which were further assembled by noncovalent hydrogen bonds into a three-dimensional (3D) supramolecular framework. Through ultrasonic treatment in isopropyl alcohol, Cd-1 was exfoliated to afford an ultrathin CP-based 2D nanosheet (Cd-1-NS) with a thickness of less than 1.8 nm. Compared to the bulk materials, the prepared Cd-1-NS exhibited enhanced fluorescence emission properties and superior sensing performance toward glyphosate (Glyph) in water with high selectivity, sensitivity, anti-interference, fast response, and good recyclability via the turn-off effect. The limit of detection (LOD) of Cd-1-NS for Glyph was as low as 41 nM (7 ppb) in the low-concentration range of 0−2.4 μM. In addition, the Cd-1-NS also showed excellent practicability and reliability for the detection of Glyph in real samples, including lake water, tap water, cabbage, and watermelon skin, and could realize the rapid visualized sensing of Glyph residues on the surfaces of vegetables and fruits.
