Abstract
Aluminium (Al3+) and hypochlorite (ClO−) have toxic effects on plants, affecting various physiological processes and ultimately impacting plant growth and development. Hence, the preparation of a smart tool for the detection of hypochlorite (ClO−) and Aluminium (Al3+) in water, a dual-target fluorescent chemosensor APC (anthracene-pyridine conjugate) has been synthesized. APC holds a unique diimine character when compared with a few similar diimine and interacts with both Al3+ and ClO− through charge transfer and chemodosimetric mechanisms to display green and blue fluorescence, correspondingly.The detection limits of APC for Al3+ and ClO− are 0.68 µM and 0.25 µM, respectively. The binding ratio between APC and Al3+ has been determined as 1:1 from Jobs plot analysis. The sensing mechanisms of APC with Al3+ and ClO− have been established by UV–visible, 1H NMR titration, HRMS analysis and theoretical calculations. This method has been successfully employed to examine the consequences of continued exposure to high concentrations of aluminium and hypochlorite on marigold and lettuce plants, respectively.
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.
