“…However, the excimer emission appeared to be strongly dependent on the solvent system used. 89 Figure 5 shows a clear enhancement of the excimer formation in less polar solvents such as toluene, THF, or DCM. By increasing the polarity of the solvents, the In 3+ -S1 complex displays a decrease of the emission presumably due to nonradiative relaxation and solvent interactions inducing a lack of flexibility within the sensor and inhibiting the excimer formation.…”

Sequential Multiple-Target Sensor: In³⁺, Fe²⁺, and Fe³⁺ Discrimination by an Anthracene-Based Probe

Indium is a nonphysiological toxic metal widely used in industry. While misunderstood, its toxicity is proposed to be linked to a perturbation of Fe 3+ homeostasis through the binding of In 3+ ions to essential iron metalloproteins such as transferrins. Therefore, the monitoring of In 3+ and Fe 3+ in biological environments is of prime interest for both basic research and diagnosis. Here we report the design of a salen-type anthracene-based probe able to selectively sense and discriminate In 3+ and Fe 2+/3+ ions by fluoro-colorimetry.1

“…Solvent is an important factor which can affect the coordination of metal ions and ligands. [31,32] The absorption intensity of 100 μM Cu 2+ detected in various solvents were assayed and shown in Figure 1B. It is clear to see that Cu 2+ have more strong coordination with TMB in ethanol and acetonitrile.…”

It is of great meaning to develop a facile, reliable and sensitive method to detect copper ions in water. In the study, a facile method has been developed for rapid and sensitive detection of Cu 2+ . An interesting phenomenon has been observed that 3,3',5,5'-tetramethylbenzidine (TMB) ethanol solution can be extremely fast passed from colorless to yellow once Cu 2+ ions are added. It easily occurs to us that Cu 2+ can be quantitatively determined via the absorbance at 904 nm of the color changed TMB solution. More importantly, some specific anions (Cl -, Br -) can significantly enhance the absorption intensity. Under the optimized experimental conditions, this method exhibits a good linear response range for Cu 2+ from 0.5 to 100 μM, with the detection limit of 93 nM. Moreover, the possible detection principle has been explored. It is worth mentioning that the color change can be clearly observed by naked eyes for the detection of 1 μM Cu 2+ , which is far below the threshold limit of Cu 2+ in drinking water suggested by World Health Organization. It means that this method possess great promise for on-site Cu 2+ detection.

“…Therefore, the development of fluorescent chemosensors (due to high sensitivity of fluorescence spectroscopy, easy operation, visual simplicity [14], instantaneous response, real-time detection [15], and a variety of fluorophores [16]) for the detection of Cu 2+ ions is of great importance [17]. On the other hand, the availability of a variety of fluorophores and the selectivity of such fluorescent probes still remain a great challenge, as many recently reported chemosensors for cations demonstrated a change in their fluorescent features after binding with more than one ion [18][19][20].…”

Herein, we have investigated principally with the use of UV and fluorescence (steady-state and time-resolved) spectroscopy the interactions between selected pentapeptides with tyrosine residue (EYHHQ, EHYHQ, EHHQY, and KYHHE) and various metal ions (Cu2+, Mn2+, Co2+, Ni2+, Zn2+, Cr3+, Cd2+, Ag+, Pb2+, Sr2+, Ba2+, Ca2+, Mg2+, Al3+, Fe2+, and Ga3+) in order to establish the relationship between the position of a tyrosine residue in the peptide sequence and the metal ion-binding properties. Among the peptides studied, EHYHQ was evaluated as an efficient and selective ligand for developing a chemosensor for the detection of copper(II) ions. While significant fluorescence emission quenching was observed for that peptide in the presence of Cu2+ cations, other metal cations used at the same and at considerably higher concentrations caused a negligible change of the fluorescence emission spectrum, indicating a high selectivity of EHYHQ for Cu2+ ions. Under optimum conditions, fluorescence intensity was inversely proportional to the concentration of Cu2+ ions. The limit of detection of Cu2+ ions with the use of EHYHQ was determined at the level of 26.6 nM. The binding stoichiometry of the complexes of the studied peptides with Cu2+ ions was evaluated spectrophotometrically and fluorimetrically (as in the case of EHYHQ confirmed by mass spectrometry) and found to be 1:2 (Cu2+-peptide) for all the investigated systems. Furthermore, the stability constant (K) values of these complexes were determined. The reversibility of the proposed Cu2+ ions sensor was confirmed, the pH range where the sensor acts was determined, while its analytical performance was compared with some other reported recently fluorescent sensors. The mechanism of the interactions between EHYHQ and Cu2+ was proposed on the basis of NMR spectroscopy investigations.
