Abstract

In this work, we developed a fluorescence probe HCPM with AIE effect. The probe HCPM in solid state showed obvious fluorescence colormetric response from orange-red to green for cadaverine vapor with high selectivity and could quantitative detect cadaverine vapor and a visual detection platform was constructed by combining it with a smartphone. Also, the probe HCPM exhibited significant fluorescence colormetric responses for 12 BAs and could detect the different concentrations of cadaverine in EtOH/H₂O (1/9, v/v, pH = 7.4) solution. Moreover, the probe HCPM was loaded on the test paper and silica gel plate as sensing label, which could be used to visual detect the freshness of pork and shrimp.

用于视觉监测食物新鲜度的固体AIE传感器

在这项工作中，我们开发了具有AIE效应的荧光探针HCPM。固态探针HCPM对尸胺蒸汽具有明显的橙红到绿色的荧光比色响应，具有较高的选择性，可以定量检测尸胺蒸汽，并与智能手机结合构建了可视化检测平台。此外，探针HCPM对12种BAs具有显著的荧光比色响应，可以检测EtOH/H2O （1/9, v/v, pH = 7.4）溶液中不同浓度的尸胺。并将探针HCPM作为传感标签加载在试纸和硅胶板上，用于对猪肉和虾的新鲜度进行视觉检测。

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.
