Abstract

A new multi-target sensor, (E)-2-(benzo[d]isoxazol-3-yl)-N’-(4-(diethylamino)-2-hydroxybenzylidene)acetohydrazide (BIDA), was designed using benzoisoxazole, characterized by its simplicity and ease of synthesis. An “off-on” effect towards Ga³⁺ ions in DMSO/H₂O tris buffer and an “off-on-off” effect towards Mg²⁺ and Mn²⁺ ions in ACN/H₂O tris buffer were exhibited by BIDA. Simultaneously, Ga³⁺, Mg²⁺ and Mn²⁺ ions were detected by BIDA, with lower detection limits of 1.91 × 10⁻⁸ M, 6.30 × 10⁻⁹ M and 1.95 × 10⁻⁸ M. The 1:2 chelation stoichiometry of the complexes formed between the sensor and Ga³⁺, Mg²⁺ and Mn²⁺ was confirmed using analysis of Job’s plot and mass spectrometry. Different concentrations of analyte ions in environment water samples were effectively identified by the BIDA sensor, and an independent, user-friendly paper sensor was successfully developed for their 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.
