Vanillinyl‐hydrazone Schiff base, 2,6‐Bis‐[(2‐hydroxy‐3‐methoxy‐benzylidene)‐hydrazonomethyl]‐4‐methyl‐phenol (PHV) is characterized by spectroscopic techniques and serves as selective and sensitive fluorescence sensor at different emission wavelength for Zn2+ (λem, 546 nm), Cd2+ (λem, 567 nm) and Mg2+ (λem, 625 nm) in DMSO/H2O medium (9 : 1, v/v) in presence of large number of available cations. The probe also displays selective turn‐on fluorescence sensitivity to I− (λem, 635 nm) in THF medium. Density Functional Theory (DFT) computation techniques are used to explain some of the obtained experimental observation.

Optical Anion Receptors with Urea/Thiourea Subunits on a TentaGel Support

Two simple chemosensors with urea (L1) and thiourea (L2) groups were synthesized and studied by different spectroscopic techniques. Both receptors can sense acetate (Ac – ), dihydrogen phosphate (H 2 PO 4 – ), and fluoride (F – ) anions, accompanied by changes in UV–vis and 1 H NMR spectra, and an optical response is observed as a color change of the solutions due to deprotonation and hydrogen-bonding processes. Also, L1 and L2 were supported on TentaGel resins (R1 and R2), and their fluoride-sensing properties in DMSO and water solutions were studied. Interestingly, R2 can sense fluoride ions in sample solutions of 100% water.

“…Hence, the choice and design of the sensing material are main points concerning sensor application performance. Fluorescence sensors were applied in the measurement of various targets, such as small molecules [89,90], cations [91,92], anions [93,94], and biomolecules [95,96]. The detection of pollutants in the environment and food is crucial because such chemical species pose serious health risks.…”

The high speed of contaminants growth needs the burgeoning of new analytical techniques to keep up with the continuous demand for monitoring and legislation on food safety and environmental pollution control. Metal-organic frameworks (MOFs) are a kind of advanced crystal porous materials with controllable apertures, which are self-assembled by organic ligands and inorganic metal nodes. They have the merits of large specific surface areas, high porosity and the diversity of structures and functions. Latterly, the utilization of metal-organic frameworks has attracted much attention in environmental protection and the food industry. MOFs have exhibited great value as sensing materials for many targets. Among many sensing methods, fluorometric sensing is one of the widely studied methods in the detection of harmful substances in food and environmental samples. Fluorometric detection based on MOFs and its functional materials is currently one of the most key research subjects in the food and environmental fields. It has gradually become a hot research direction to construct the highly sensitive rapid sensors to detect harmful substances in the food matrix based on metal-organic frameworks. In this paper, we introduced the synthesis and detection application characteristics (absorption, fluorescence, etc.) of metal-organic frameworks. We summarized their applications in the MOFs-based fluorometric detection of harmful substances in food and water over the past few years. The harmful substances mainly include heavy metals, organic pollutants and other small molecules, etc. On this basis, the future development and possible application of the MOFs have prospected in this review paper.
