Abstract Hugo Schiff (1864), was the first who synthesized Schiff bases by the condensation
reaction of primary amines with carbonyl compounds (aldehyde or ketone). Schiff bases …

Due to the risks that water contamination implies for human health and environmental
protection, monitoring the quality of water is a major concern of the present era. Therefore, in …

This article presents a simple, low-cost, eco-benign, and portable naked-eye solid-state
sensor for the selective and sensitive colorimetric detection and recovery of ultra-trace …

Chemosensors are synthetic chemical compounds that have the ability to selectively bind
with analytes of interest and produce detectable changes in, for example, their color …

Pyridine derivatives are the most common and significant heterocyclic compounds, which
play an important role in various fields ranging from medicinal to chemosensing …

Differentially selective molecular sensors that exhibit differential response toward multiple
analytes are cost-effective and in high demand for various practical applications. A novel …

A novel acylhydrazone coumarin fluorescent chemosensor C 4 for detection of Ni 2+ was
designed and synthesized. The experimental results revealed a low detection limit of 2.1× …

In this study, by coupling benzothiazole and spiropyrans, three fluorescent probes HBT-pH
1, HBT-pH 2, and HBT-pH 3 were developed for pH variation monitoring. All these probes …

A novel fluorescent chemosensor (E)-2-((3-((bis (pyridin-2-ylmethyl) amino) methyl)-2-
hydroxy-5-methylbenzylidene) amino)-3′, 6′-bis (diethylamino) spiro [isoindoline-1, 9 …

A small series of simple pyrazoline and pyrazole based sensors, all derived from the same
chalcone precursors, were synthesised, characterised and screened for their fluorescence …
