“…The AIE feature of a π-conjugated cyanostilbene derivative of (Z)-2-(4-nitrophenyl)-3-(4-(vinyloxy)phenyl)acrylonitrile, Hg-59 ( Fig. 50), was advantage taken of by Wang et al in their design of a new sensing modality (Wang et al 2015). The sensing properties of the designated probe compound were carried out in THF/H 2 O (2:8, v/v).…”

Though it has not been shown to deliver any biological importance, mercuric(II) ion (Hg 2+) is a deleterious cation which poses grievous effects to the human body and/or the ecosystem, hence, the need for its sensitive and selective monitoring in both environmental and biological systems. Over the years, there has been a great deal of work in the use of fluorescent, colourimetric, and/or ratiometric probes for Hg 2+ recognition. Essentially, the purpose of this review article is to give an overview of the advances made in the constructions of such probes based on the works reported in the period from 2011 to 2019. Discussion in this review work has been tailored to the kinds of fluorophore scaffolds used for the constructions of the probes reported. Selected examples of probes under each fluorophore subcategory were discussed with mentions of the typically determined parameters in an analytical sensing operation, including modulation in fluorescence intensity, optimal pH, detection limit, and association constant. The environmental and biological application ends of the probes were also touched where necessary. Important generalisations and conclusions were given at the end of the review. This review article highlights 196 references. Keywords Mercuric(II) ion (Hg 2+) • Fluorescent probes • Colourimetric probes • Ratiometric probes • Hg 2+-selective probes • Sensing

“…[45][46][47][48][49][50][51][52] We have also constructed several uorescent probes which possess signicant AIE feature. [53][54][55] It is well known that the familiar excited state intramolecular proton transfer (ESIPT) uorophore 2-(2 0hydroxyphenyl)-benzothiazole (HBT) has been widely used to construct uorescent probes, owing to its large Stokes shi and high photostability. [56][57][58] Moreover, HBT has typical AIE properties by virtue of ESIPT and restriction of intramolecular motion (RIM) mechanisms.…”

A novel quinoline-functionalized homooxacalix [3]arene L was synthesized via Click chemistry and its chemosensing properties with various metal ions were investigated. The chemosensor L exhibited a high selectivity and antidisturbance for Fe 3+ amongst environmentally and biologically relevant metal ions, leading to a prominent 'off-on' type fluorescent signalling behaviour. Our studies demonstrated that the detection limit on fluorescence response of the sensor to Fe 3+ is in the 10 −7 M range. The mechanism of the interaction between the L and Fe 3+ has been investigated in detail by 1 H NMR spectroscopic titration experiments.
