摘要

钯在许多领域都有重要的应用。然而，它造成了许多重大的环境和生物危害，强调了开发有效的方法来检测环境和生物系统中的钯的必要性。本文以苯并噻吩酮为基础，以碳酸烯丙基为响应位点，设计了一种新型的钯响应荧光探针TM-BTPA-Pd。该探针具有明显的Stokes位移（251 nm）、良好的灵敏度（0.12 μM）、快速的响应时间（30 s以内）、高选择性和稳定性。此外，探头通过颜色识别软件实现了Pd0的便携式检测，可以识别颜色变化。这些研究已经证明了探针在监测活细胞、斑马鱼和实际水样中的钯水平方面的有效性。这些结果强调了该探针在环境和生物监测中的应用潜力。

Development of a benzothianone-based NIR fluorescent probe and its application of Pd0 detection in bioimaging and smartphone-assisted water samples

Palladium has significant applications across a range of fields. Nevertheless, it poses a number of significant environmental and biological hazards, underscoring the necessity of developing effective methods for the detection of palladium in both environmental and biological systems. In this paper, a novel palladium-responsive fluorescent probe TM-BTPA-Pd was designed based on benzothianone, with allyl carbonate serving as the response site. The probe showed a remarkable Stokes shift (251 nm), excellent sensitivity (0.12 μM), a rapid response time (within 30 s), high selectivity, and stability. Moreover, the probe enabled the portable detection of Pd⁰ through color recognition software, which can discern color alterations. The studies have demonstrated the efficacy of the probe in monitoring palladium levels in living cells, zebrafish, and actual water samples. These results underscore the potential of this probe for applications in environmental and biological monitoring.

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.
