An experimental and theoretical study of a new sensitive and selective Al3+ Schiff base fluorescent chemosensor bearing a homopiperazine moiety

Development of multi-analyte responsive sensors: optical discrimination of arsenite and arsenate ions, ratiometric detection of arsenite, and application in food and water samples

“…[18][19][20][21][22][23] Most of these chemosensors were designed for monitoring the environment-polluting ions with precise detection and quantification. 20,[24][25][26][27][28][29][30] Among various environment-polluting ions, arsenic species are highly threatening to the ecological system and human health. 31 Groundwater pollution by arsenic compounds is a frequent concern due to their extreme toxicity.…”

A Highly Efficient and Selective Glycine Based Schiff Base Fluorescent Probe for Dual Sensing of Zn(II) and Cu(II) and its Antibacterial Activity and BSA Interaction Studies

“…[15,16] Schiff base is capable of imparting notable sensing properties along with enhanced stability for specific metal ions owing to the efficient electronic and geometric characteristics of the host-guest complexation. [17] The presence of binding sites viz., N and O in the salicylaldimine based Schiff base enable the probe to bind to the metal ions efficiently resulting into turn-on and turn-off florescence revealing selectivity to particular ions. [8] The turn-on effect of the fluorescence intensity on addition of the metal ion is attributable to the increase in rigidity and planarity of the compound resulting into inhibition of photoinduced electron transfer (PET) whereas the reverse PET results into the turn-off response of the fluorophore.…”

“…The nitrogen atom of azomethine moiety (C=N) in Schiff base also exhibits a strong affinity for transition metal ions [15,16] . Schiff base is capable of imparting notable sensing properties along with enhanced stability for specific metal ions owing to the efficient electronic and geometric characteristics of the host‐guest complexation [17] …”

Design, synthesis, and density functional theory studies of a new selective chemosensor for Pb2+

“…Although these methods have shown good performance in the determination of Pb 2+ , they require a controlled laboratory environment, a long operation time, and pure chemicals. In order to solve these problems, electrochemical sensors or molecular probes were designed for specific purposes with the help of the theoretical branch of host-guest supramolecular chemistry [ 15 , 16 ].…”
