“…The as‐intended organic probe RePr contains a resorufin fluorophore and a propionate block with an ester bridge. It can be prepared in one step; resorufin sodium salt was treated with propionyl chloride in the presence of triethylamine to get 80% yield of RePr ,. The OA‐capped UCNPs were prepared as per the earlier reported procedure with slight modification ,.…”

Hydrazine is a noxious environmental pollutant, which can be easily absorbed through skin, respiratory and oral paths of exposure and leads to mutagenic and carcinogenic diseases, which demands for the progress of advanced detection methods. In this regard, we report a new detection platform based on luminescence resonance energy transfer (LRET) for the detection of hydrazine (N 2 H 4 ) in environmental samples, where anti-Stokes shift luminescence having optical sensing system is built with upconversion nanophosphors (UCNPs, donor) modified by resorufin propionate (RePr, acceptor). Herein UCNPs were used as an excitation host to significantly minimize the photobleaching of RePr. Upon interaction with N 2 H 4 , the green upconversion luminescence (UCL) intensity of hybrid nanoprobes (RePr-UCNPs) gradually decreases, since the green emission is in resonance with the absorbance of resorufin, whereas the red emission intensity was intact. Hence, green emitting optical sensing system shows red luminescence in the presence of hydrazine. This organic-inorganic hybrid sensing system has been utilized for the sensing of hydrazine in various environmental samples and the obtained results are compared with the sensing efficiency in distilled water. This anti-Stokes shift luminescent hybrid sensing system would be a promising candidate to be utilized in environmental protection, water treatment and safety inspection.

“…The structures of these fluorescent hydrazine probes are summarized in Figure . However, it should be pointed out that, the acetyl group located on the aromatic phenol is also a reaction site for BO 3 − anion, and several fluorescent probes have been develop for BO 3 − ions based on the acetyl recognition moiety, indicating that BO 3 − may interfere with the hydrazine detection by using this type of probe.…”

Recent progress in the development of fluorescent probes for hydrazine

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.

“…Recently, there has been an upsurge of interest in chemodosimeter based chemical sensing through M a n u s c r i p t 2 a specific irreversible chemical reaction between dosimetric molecules and the target species, leading to the release of a fluorescent or colored product [27][28][29]. Reaction-based chemodosimeters have been developed to achieve emission enhancement by reacting with Cu 2+ to yield fluorescent products which have little affinity to Cu 2+ , thus avoiding the challenge of paramagnetic nature of Cu 2+ .…”
