“…The addition of all other metal ions notably quenched the fluorescence intensity of SC97 , whereas adding Zn 2+ ions to probe SC97 solution resulted in more significant fluorescence quenching by about 60‐folds. In this case, on one side all other metal ions exhibited partial quenching of fluorescence, while on the other hand, the quenching impact of Zn 2+ ions on SC97 was about 100% [158] …”

“…Synthesis of probe SC97. [158] For the synthesis, 7-diethylaminocoumarin-3-aldehyde and 3-amino-7-hydroxycoumarin were mixed in hot 100% C 2 H 5 OH for generating crimson precipitates to use in the creation of coumarin Schiff base complex SC98. After 6 hours of reflux agitation, the precipitate was filtered, washed three times using hot ethanol, and recrystallized with the help of DMF/H 2 O (v/v, 1/3) to give scarlet crystals with 86% yield.…”

Coumarins, due to their intense and persistent emission of fluorescence, structural flexibility, and excellent biocompatibility, have become a popular choice in developing new fluorescent chemosensors. Coumarins have long been used for sensing anions, cations, chemically reactive nitrogen, oxygen, sulfur-containing species, and small molecules. They have also been shown to have applicability in imaging, biology, and medical research. Due to the widespread use and excellent biological activity, hundreds of such coumarin motifs have either been isolated from nature or synthesized in a laboratory. This review covers all the developments pertaining to the synthesis and use of coumarin for sensing a variety of metal ions (alkali, alkaline earth, transition, heavy, and noble metal ions). This comprehensive review includes an overview of the coumarin-based chemosensor's pH limit, detection limit, and binding mode. A brief explanation of the stoichiometric ratio between metal and chemosensor moiety and the applicability of each chemosensor is also given.

“…Copper ion and zinc ions are essential trace elements in the human body, which play an important role in human health, especially the catalytic auxiliary role in various biological processes such as the function of many cellular enzymes and proteins [10][11][12]. However, when the concentration of absorbed ions is unbalanced, the homeostasis in cells will be affected, leading to a series of diseases [13][14][15].…”

Preparation of Large Conjugated Polybenzimidazole Fluorescent Materials and Their Application in Metal Ion Detection

et al. 2021

A new type of conjugated polybenzimidazole (CPBI) was synthesized through a simple polycondensation reaction without metal catalysis, and N-alkylation modification was carried out to solve the problems of solubility and fluorescence properties. A series of nano-microsphere polymers CPBIn with large conjugation, good solubility, and strong fluorescence has been successfully used as “turn-off” fluorescent probes for the first time. The results show that, under suitable N-alkylation conditions, the obtained CPBIn can be used as a highly sensitive and selective fluorescent probe for the detection of Cu2+ and Zn2+ at the same time, and their detection limits are both nM levels. In addition, CPBI2 can be designed as an ultra-sensitive IMPLICATION logic gate at the molecular level, cyclically detecting Cu2+. With the test paper containing CPBI2, easy and quick on-site detection can be achieved. This research provides a new idea for the brief synthesis of multifunctional materials.

“…27 Various fluorescence probes for recognizing Zn(II) ions, based on quinolone, phthalimide, naphthalene, coumarin, and carbazole, have been successfully developed. [28][29][30][31][32] However, these exhibit limitations like poor solubility, non-biocompatibility, and expensive protocol. To fulfill sustainable development goals, herein, we have represented the synthesis and characterization of novel pseudopeptidic soft materials 1-3 for selective recognition of zinc (II).…”
