Abstract

Zinc ions (Zn²⁺) and cadmium ions (Cd²⁺) are widely present in our production and life, which are closely related to human health and environmental protection. Hence, it is essential to detect their concentrations. Herein, we developed a convenient and reliable small-molecule fluorescent probe based on Schiff base of dicyanisophorone and 2-hydrazinopyridine. This probe can be able to selectively detect Zn²⁺ and Cd²⁺, showing the advantages of near-infrared emission (the maximum emission wavelength: 668 nm), good selectivity, high sensitivity (the detection limits: 0.21 µM and 0.31 µM, respectively) and rapid response (15 s). It has excellent potential for rapid testing and visual tracking of Zn²⁺ and Cd²⁺ in aqueous solution and living cells.

近红外荧光双传感Zn2+和Cd2+的二氰异佛隆探针

锌离子(Zn2+)和镉离子(Cd2+)广泛存在于我们的生产和生活中，与人类健康和环境保护密切相关。因此，检测它们的浓度是必要的。本文以双氰异佛酮和2-肼吡啶的希夫碱为基础，研制了一种方便、可靠的小分子荧光探针。该探针可选择性检测Zn2+和Cd2+，具有近红外发射(最大发射波长为668 nm)、选择性好、灵敏度高(检出限分别为0.21µM和0.31µM)、响应速度快(15 s)等优点，在水溶液和活细胞中Zn2+和Cd2+的快速检测和视觉跟踪方面具有良好的潜力。

期刊介绍： Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in chemistry, medicine, biology, and materials science. The journal publishes original scientific papers that feature high-quality spectroscopic data and analysis. From the broad range of optical spectroscopies, the emphasis is on electronic, vibrational or rotational spectra of molecules, rather than on spectroscopy based on magnetic moments. Criteria for publication in SAA are novelty, uniqueness, and outstanding quality. Routine applications of spectroscopic techniques and computational methods are not appropriate. Topics of particular interest of Spectrochimica Acta Part A include, but are not limited to: Spectroscopy and dynamics of bioanalytical, biomedical, environmental, and atmospheric sciences, Novel experimental techniques or instrumentation for molecular spectroscopy, Novel theoretical and computational methods, Novel applications in photochemistry and photobiology, Novel interpretational approaches as well as advances in data analysis based on electronic or vibrational spectroscopy.
