“…A rhodamine-based conjugated dyad probe (19) has been synthesized by Stalin and coworkers (Scheme 6) [171]. The authors claimed that the FRET mechanism between the rhodamine and pyridine conjugated dyad is responsible for the emission observed upon the coordination of Cd 2+ ions in the organic-aqueous system (CH 3 CN:HEPES buffer 2:8, v/v, pH 7.2, 10 mM).…”

“…Therefore, by varying the ratios of water and organic solvent the mechanism could be turned on and off. The triazole moiety was used as the Lewis basic site to coordinate the Cd 2+ ions [171]. In solutions containing ≤50% water, Another popular fluorescent mechanism that is being used in molecular probe design is aggregation induced emission (AIE), a similar mechanism to excimer formation.…”

Fluorescence sensing, of d-block elements such as Cu2+, Fe3+, Fe2+, Cd2+, Hg2+, and Zn2+ has significantly increased since the beginning of the 21st century. These particular metal ions play essential roles in biological, industrial, and environmental applications, therefore, there has been a drive to measure, detect, and remediate these metal ions. We have chosen to highlight the low molecular weight fluorescent probes (LMFPs) that undergo an optical response upon coordination with the group 12 triad (Zn2+, Cd2+, and Hg2+), as these metals have similar chemical characteristics but behave differently in the environment.

“…Since the report of Czarnik's Cu 2+ -sensor (26), various rhodaminebased turn-on fluorescent sensors have been reported for Hg 2+ (27), Fe 3+ (28), Cr 3+ (29), Cu 2+ (30), and Pd 2+ (31). So far, a few rhodaminebased turn-on fluorescent sensors have been reported for Cd 2+ (32)(33)(34)(35)(36). However, some of these sensors also have some technical drawbacks such as interference with other metal ions (36) and sensing to hydrogen ions (33).…”

Fluorescent sensors have attracted an important interest due to their advantages such as high selectivity, rapid response, easy use, etc. In this study, a rhodamine based fluorescent sensor, RhDP, was synthesized, and used for selective detection of Cd 2+ ions. The sensor responds to Cd 2+ via the coordination induced fluorescence activation (CIFA) mechanism. RhDP gives a very fast and reversible fluorescence response to Cd 2+ in the presence of the metal ions tested. The complex stoichiometry between RhDP and Cd 2+ was found to be 1:1 and the binding constant was calculated as 2.70 × 10 7 M-1 in acetonitrile (ACN)/HEPES buffer (10 mM, pH: 7.05, v/v 1:1). The fluorescent detection limit of RhDP for Cd 2+ was found to be 0.218 µM, which gave a marked sensitivity towards Cd 2+ .

“…Recently, plenty of attention has been taken to the recognition, of heavy metal ions due to their immediate diffusion as environmental contaminants to the surroundings [1]. Thus, the development of highly selective and efficient signaling systems is fundamental for the identification of various chemical species [2]. The fluorescence sensors techniques as a promising and powerful tool for the sensing of heavy metal ions in trace amounts are currently of significant importance for chemistry, environmental science and biology [3].…”

The design and synthesis of sensitive and selective luminescent materials as chemical sensing agents is a fundamental goal in fluorescence assays. Considering high porosity, large surface area, excellent photoluminescence property of metal-organic frameworks (MOFs), luminescent properties of a microporous azine-functionalized MOF, TMU-16, dispersed in different metal ions have been investigated systematically. The TMU-16 displays superb luminescence emission, and it can detect Fe(III) and Cd(II) ions with high selectivity, excellent sensitivity, and short response time (<1 min). The emission intensities of TMU-16 were quenched upon the addition of Fe(III) and increased upon the addition of Cd(II). The effect of other metal ions on the fluorescence intensity of the MOF was also studied and other metal ions showed low interference response in recognition of Fe(III) and Cd(II). More importantly, this is the first example of MOF-based luminescent sensor as efficient multifunctional fluorescence material which can use for selective sensing of Fe(III) and Cd(II) ions.
