“…Two naphthalimide-appended fluorescent probes, Hg-2 and Hg-3 ( Fig. 4), were devised and reported by Li and his research group members (Li et al 2016). In phosphate buffer, the two compounds display ultra-high-level sensitivities and selectivities for Hg 2+ detection.…”

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.

“…1,8‐Naphthalimide derivatives have aroused attention when constructing the fluorophore moieties of sensors because of their appealing features of high photostability and quantum yield, they also have strong absorption band in the visible region and large Stokes’ shifts . Accordingly, there has been many applications of 1,8‐naphthalimide derivatives as components of liquid crystal displays, laser active medium, fluorescent markers in biology, photoinduced electron transfer chemosensors, electroluminescence devices and fluorescence switchers and probes .…”

The present study reports the development of a new 1,8-naphthalimide-based fluorescent sensor V for monitoring Cu(II) ions. The sensor exhibited pH independence over a wide pH range 2.52-9.58, and indicated its possible use for monitoring Cu(II) ions in a competitive pH medium. The sensor also showed high selectivity and sensitivity towards the Cu(II) ions over other competitive metal ions in DMSO-HEPES buffer (v/v, 1:1; pH 7.4) with a fluorescence 'turn off' mode of 79.79% observed. A Job plot indicated the formation of a 1:1 binding mode of the sensor with Cu(II) ions. The association constant and detection limit were 1.14 × 10 M and 4.67 × 10 M, respectively. The fluorescence spectrum of the sensor was quenched due to the powerful paramagnetic nature of the Cu(II) ions. Potential application of this sensor was also demonstrated when determining Cu(II) ion levels in two different water samples.

Recent progress in the development of fluorescent probes for hydrazine

et al. 2018

Hydrazine (N H ) is an important and commonly used chemical reagent for the preparation of textile dyes, pharmaceuticals, pesticides and so on. Despite its widespread industrial applications, hydrazine is highly toxic and exposure to this chemical can cause many symptoms and severe damage to the liver, kidneys, and central nervous system. As a consequence, many efforts have been devoted to the development of fluorescent probes for the selective sensing and/or imaging of N H . Although great efforts have been devoted in this area, the large number of important recent studies have not yet been systematically discussed in a review format so far. In this review, we have summarized the recently reported fluorescent N H probes, which are classified into several categories on the basis of the recognition moieties. Moreover, the sensing mechanism and probes designing strategy are also comprehensively discussed on aspects of the unique chemical characteristics of N H and the structures and spectral properties of fluorophores.
