“…Fluorescent probe 6 (Figure 2) was designed by Yu and his group 52 for the determination of Zn 2+ ions in an aqueous solution. A rapid increase in the fluorescent emission intensity was observed with Zn 2+ ions in the solution that was very specific towards the Zn 2+ ions.…”

In the past few decades, zinc has received great attention towards the scientific community due to its supreme importance in living organisms. Zinc is a trace element that is vitally important to all living organisms and it plays an important role in the immune system, wound healing, growth and division. Therefore, the development and advancement of simple, efficient, selective and inexpensive chemosensors for the determination of Zn2+ is of paramount prerequisite. Chemosensors have unique properties that are used for the determination of several metal ions specifically and selectively. This review summarizes the Schiff base chemosensors designed and synthesized by several research groups from the year 2018. The interaction of these probes with zinc metal ions has also been discussed briefly in this review. Furthermore, the comparison of detection limits of these probes demonstrated that the Schiff base probe 34 possessing two benzothiazole moieties exhibits the lowest detection limit (0.00028 µM) indicating it to be the lead compound in the determination of Zn2+ ions in near future.

Construction of fluorescent probes for zinc ion (Zn2+) and cadmium ion (Cd2+) is significant for the safety of humans. However, the discriminating recognition of Zn2+ and Cd2+ by a single probe remains challenging owing to their similar properties. Herein, a novel deoxycholic acid derivative containing 8‐hydroxyquinoline fluorophore has been facilely synthesized through click chemistry to form a clamp‐like probe. Using its perfect bonding cavity from 1,2,3‐triazole and quinoline, this molecule showed favorable solvent‐dependent fluorescent responses and distinguished Zn2+ and Cd2+ in different solvents. In ethanol aqueous solution, it displayed good selectivity and ratiometric fluorescence to Zn2+ with 30 nm spectroscopic red‐shifts. In acetonitrile aqueous solution, it exhibited good selectivity and ratiometric fluorescence to Cd2+ with 18 nm spectroscopic red‐shifts. Moreover, the unique microstructural features of the probe in assembly were used to reflect its recognition processes. Due to its merits of low detection limit and instant response time, the probe was utilized for sensing Zn2+ and Cd2+ in water, beer and urine with high accuracy. Meanwhile, this probe served as a handy tool and was employed to obtain inexpensive test strips for the prompt and semiqualitative analysis of Zn2+ and Cd2+ with the naked eye.
