“…It shows that the probe is appropriate for measuring Al(III) in water samples. Table 2 lists the several chemosensors used to determine Al (III) [35,[47][48][49][50][51][52][53][54]. When we compared earlier approaches to our suggested method, we noticed that our method is more sensitive than others.…”

A facile, quick, and sensitive ratiometric luminescence sensor is designed for detection aluminum ions in water samples using luminescence or eye-vision. This approach relies on the emission change of the europium(III) complex with 3-(2-naphthoyl)-1,1,1,-trifluoro acetone (3-NTA) after interaction with various concentration of aluminum ions. The addition of aluminum ions suppressed the Eu(III) emission at 615 nm under 333 nm excitation, while simultaneously enhancing the ligand emission at 480 nm. Optimum detection was obtained in methanol. The quantification of aluminum ions using ratiometric method was determined by plotting the luminescence ratio (F480nm/F615nm) versus aluminum ions concentration. The calibration plot was obtained within the range 0.1–100 µM with LOD = 0.27 µM. Additionally, the concentration of aluminum ions can be estimated semi-quantitatively by visually observing the luminescence colour change of the probe from red to light green and then to dark green after being excited by a UV lamp with 365 nm. As far as we are aware, this is the first luminescent lanthanide complex-based ratiometric probe for the detection of aluminum ions. The probe showed remarkable aluminum ions selectivity relative to that of other metal ions. The suggested sensor was used effectively to identify aluminum ions in water samples with good results.

A simple colorimetric probe NPA was synthesized using 2‐aminopyrazine and 2‐hydroxynaphthaldehyde. The probe had demonstrated quick response and high selectivity toward Al3+ in the presence of other interfering metal ions. A notable color change from bright yellow to colorless was noticed on addition of aqueou solutions of Al3+ to NPA in CH3CN‐H2O (1 : 1, v/v) in physiological pH range. 1 : 1 stoichiometry in NPA‐Al3+ complex was confirmed from Job's plot and mass spectrometry. Complexation of Al3+ with the probe molecule was also confirmed using 1H NMR spectroscopy. A theoretical model structure of the complex was proposed based on density functional theory (DFT). Disruption of conjugation in the naphthalene moiety and enhancement in intramolecular charge transfer (ICT) in the complex had decreased the absorbance of NPA. Paper strip of NPA was used for fast “on‐site” detection of Al3+ without using any spectroscopic instrument. The probe was found reusable for several times. The probe can also be used for the development of molecular logic gate for the detection of Al3+.
