A fluorescent probe for the detection of Al (III) based on a novel unsymmetrical trisubstituted 1,3,5-triazine
A highly selective and sensitive assay for Al (III) has been reported. A series of unsymmetrical trisubstituted 1,3,5-triazine compounds were synthesized using a one-pot method, in which probe 8-((4,6-diphenyl-1,3,5-triazin-2-yl)oxy)quinoline (2a) utilized for the detection of aluminum ions. The fluorescence characteristics of the 2a probe were then thoroughly studied, including its selectivity towards various metal ions, solvent effects, ion interference testing, response time, maximum detection limit, Job’s curve analysis, and research on the reversibility of EDTA. The linearity of the fluorescence concentration titration was found to be good within the range of 100–300 μM with R2 = 0.981 for Al3+. The minimum detection limit was determined to be 0.29 μM and the response time was only 10 s. These results indicate that probe 2a exhibits a specific response to Al3+ and holds great potential for application in aluminum ion detection.
期刊介绍：
JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds.
All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor).
The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
