摘要

设计、合成了一种新型的2h -铬支架近红外荧光探针MCM-OMe，并对其光学性能进行了研究。MCM-OMe与肼发生亲核取代反应，颜色由红色变为蓝色，是一种新型的肼探测器。发射光谱显示MCM-OMe与其对应产物MCH之间有明显的强度偏移，表明MCM-OMe具有比例荧光特性。同时，MCM-OMe对N2H4残留具有高选择性和敏感性的酸碱耐受性。此外，该探针同样适用于水、土壤和食品中残留肼的检测。因此，我们提供了一种新型的比例荧光探针，以低成本，易于制造和操作的方式检测联氨。

Novel near-infrared 2H-chromene-based ratiometric fluorescent probe: Rapidly monitoring hydrazine in real samples

A novel near-infrared (NIR Ⅰ) fluorescent probe MCM-OMe with 2H-chromene scaffold was designed, synthesized and investigated it optical properties. MCM-OMe was identified as a novel hydrazine detector through nucleophilic substitution reaction with hydrazine, changing the color from red to blue. The emission spectra showed a clear intensity shift from MCM-OMe to its corresponding product MCH, indicating that MCM-OMe has ratiometric fluorescent property. Meanwhile, MCM-OMe exhibits acid-base tolerance with high selectivity and sensitivity to the residual N₂H₄. Moreover, the probe is equally suitable for the detection of residual hydrazine in water, soils and foods. Therefore, we provide a novel ratiometric fluorescent probe to detect hydrazine through a low-cost, easy-to-manufacture and easy-to-operate way.

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.
