“…The fluorescence intensity decreasing showed that a good linear relationship could be observed between fluorescence intensity and concentration for Eu 3+ . The association constant of sensor L1 towards Eu 3+ ion was obtained to be (2.62 ± 0.13) × 10 4 M −1 by Benesi‐Hildebrand equation and correlation coefficients ( R ) was.9901 (Figure B) …”

“…The association constant of sensor L1 towards Eu 3+ ion was obtained to be (2.62 ± 0.13) × 10 4 M −1 by Benesi-Hildebrand equation and correlation coefficients (R) was.9901 ( Figure 3B). 21,22 The Job's plot experiments were used to explore the binding stoichiometry between sensor L1 and Eu 3+ ion by changing the concentration of Eu 3+ ions([Eu 3+ ]/ ([L1] + [Eu 3+ ]) = 0,0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and 1) (see Figure s2). The maximum point was measured for a mole fraction of 0.5, which showed 1:1 complex between L1 and Eu 3+ .…”

Novel phenanthroline Schiff base fluorescent sensors L1, L2, and D1 were designed and synthesized. The sensing abilities of the compounds in the presence of metal cations (Li , Na , K , Ag , Mg , Ba , Ca , Mn , Pb , Hg , Ni , Zn , Cd , Co , Cu , Cr , Fe , Fe , Al , and Eu ) were studied by UV-vis and fluorescent spectroscopy. The compounds L1, L2, and D1 could act as Eu ion turn-off fluorescent sensors based on ligand-to-metal binding mechanism in DMSO-H O solution (v/v = 1:1, 10 mM Tris, pH = 7.4). Additionally, the L1-Eu and D1-Eu complexes could be applied as turn-on enantioselective sensors sensing of malate anion isomers with color changes. Furthermore, biological experiments using living PC-12 cells demonstrated that L1 and D1 had excellent membrane permeability and could be used as effective fluorescent sensors for detecting Eu and malate anion in living cells.

“…Therefore, there is a continuous need to develop novel, selective, sensitive, and inexpensive techniques in order to detect and discriminate from their respective habitats . The nanoparticle‐based sensory materials for Cu(II) and phosphate ion have been designed and synthesized by different research groups . It has been observed that the dipicolylamine group is considered as a potential chelator for some metal ions.…”

Truxene and its congeners due to its structural, thermal, and optoelectronic properties, has recently became important not only in biological systems but also in the field of material and environmental sciences. The remarkable scope and its applicability ranging from sensory materials to photocatalysts and fluorescent probes, forces the scientific community to think about the design and construction of architecturally simple yet much powerful novel functional materials possessing the truxene scaffold(s) in their structures. Herein, we have focused to assemble a series of ground‐breaking achievements in recent years of truxene‐based functional materials with special emphasis on their applicability in material sciences and technology. We hope that the present review will boost the current scenario of truxene and its various domains.

Low Molecular Weight Fluorescent Probes (LMFPs) to Detect the Group 12 Metal Triad

2019

View full text Add to dashboard Cite

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.
