“…There are many reports that heavy metal ions can selectively quench the fluorescence of CDs, − for example, in some reports on mercury ions, the quenching mechanism was considered to be surface oxidation due to energy transfer . In reports on iron ions, the mechanism is the neutralization of the negative charges of CDs by Fe 3+ ions .…”

In this study, blue-emission carbon dots were prepared from the legumes of the vegetable Pisum sativum Linn. by one-step carbonization. The fluorescence of a carbon dot (CDs) solution can be quenched by copper ions and recovered by ethylenediaminetetraacetic acid (EDTA). In addition, two kinds of visual fluorescent filter papers were prepared. Finally, a dual-mode fluorescence and visual fluorescent test paper was employed for the detection of copper ions and EDTA. The simple synthesis method and the high safety enable this material to have more application possibilities.

“…Colorimetric fluorescence, a novel detection method, is garnering significant attention from researchers [ 13 , 14 , 15 , 16 ]. Several sensitive fluorescent probes for iodide detection, based on changes in fluorescence intensity and colorimetry, have been reported [ 17 , 18 , 19 , 20 , 21 ]. These studies provide valuable insights for future research [ 22 ].…”

Iodine, primarily in the form of iodide (I−), is the bioavailable form for the thyroid in the human body. Both deficiency and excess intake of iodide can lead to serious health issues, such as thyroid disease. Selecting iodide ions among anions has been a significant challenge for decades due to interference from other anions. In this study, we designed and synthesized a new pincer-type acridine–triazole fluorescent probe (probe 1) with an acridine ring as a spacer and a triazole as a linking arm attached to two naphthol groups. This probe can selectively recognize iodide ions in a mixed solvent of THF/H2O (v/v, 9/1), changing its color from colorless to light yellow, making it suitable for highly sensitive and selective colorimetric and fluorescent detection in water systems. We also synthesized another molecular tweezer-type acridine–triazole fluorescent probe (probe 2) that exhibits uniform detection characteristics for iodide ions in the acetonitrile system. Interestingly, compared to probe 2, probe 1 can be detected by the naked eye due to its circulation effect, providing a simple method for iodine detection. The detection limit of probe 1 is determined to be 10−8 mol·L−1 by spectrometric titration and isothermal titration calorimetry measurements. The binding stoichiometry between probe 1 and iodide ions is calculated to be 1:1 by these methods, and the binding constant is 2 × 105 mol·L−1.

This work demonstrates the preparation of (N, S)‐co‐doped fluorescent carbon dots (N, S‐CDs) for mercury ions (Hg2+) detection. This new fluorescent probe based on N, S‐CDs using dopamine hydrochloride (DA) and L‐cysteine (L‐Cys) as raw materials was reported for the first time. The resulting N, S‐CDs exhibited excellent specificity and selectivity towards Hg2+ and could distinguish them from 26 anions and cations, including Cd2+, Pb2+, and Cr2O72−. The sensor demonstrated high‐intensity fluorescence quenching at ∼457 nm under the Hg2+ presence and the ability to detect Hg2+ in the 0.05‐0.5 μM range with a 9.37 nM detection limit. The innovations of this work are to offer a method for rapid monitoring of Hg2+ in the environment, besides inventing a new fluorescent probe based on N, S‐CDs.
