Formation of an emissive telluroxide promoted by Hg2+ in aqueous environment: A new naked-eye and ratiometric rhodamine dimer fluorescent mercury(II) probe

A BOPHY based fluorescent probe for Hg2+via NTe2 chelation

“…Paper nM, which is lower than that reported for organotelluriumbased probes. 40,[46][47][48] Hence, probe 3 can effectively detect Hg 2+ metal ions in a nanomolar concentration range.…”

Design strategies and applications of novel functionalized phenazine derivatives: a review

“…Impressively, it was of great scientific value and practical significance to monitor specific processes. 114–121 As early as 2018, Su and Mei et al 122 reported a ratiometric indicator 20 , applied in monitoring the gelation process. Firstly, as shown in Scheme 10, adduct 20 as a gelator was obtained by introducing a gelating moiety cholesterol into the VIE-active dihydrophenazine, where cholesterol acted as a steroidal group and dihydrophenazine served as a fluorescent signaler.…”

Discussions of Fluorescence in Selenium Chemistry: Recently Reported Probes, Particles, and a Clearer Biological Knowledge

“…It is proposed that the Te center is directly chemically oxidized by Hg 2+ (as opposed to electrochemical oxidation). The presence of potential interference in the form of oxidant species such as H2O2, − OCl, − ONOO, KO2, as well as NO2 − were tested, reported, and discussed [68]. A tellurium containing probe was studied and reported by Soares-Paulino et al; this molecule is emissive; while perhaps not surprising, based on previous literature, the Hg 2+ involvement is important from a health and environmental perspective.…”

The presence of potential interference in the form of oxidant species such as H 2 O 2 , − OCl, − ONOO, KO 2 , as well as NO 2 − were tested, reported, and discussed [68]. A report by Tian et al involved the preparation of a novel selenadiazole derivative by a one-pot reaction.…”
