Abstract

Vanillin and ortho-vanillin are the most important flavoring additives used in the food industry at a large scale. Herein, the aggregation-induced emission (AIE) behavior of commercially available 3-hydroxy-2-naphthohydrazide (3HN) was explored and applied for the detection of vanillin and ortho-vanillin. The weakly fluorescent 3HN in DMSO showed fluorescence enhancement at 500 nm with the increase in HEPES or PBS buffer (pH 7.4) fractions in DMSO. The 3HN in DMSO containing 30% HEPES buffer is used as Probe 1 for the selective detection of ortho-vanillin. Probe 1 showed a new fluorescence emission at 415 nm for ortho-vanillin without altering the probe emission at 500 nm. With high specificity, Probe 1 can detect ortho-vanillin down to 0.3 μM. In contrast, 3HN in DMSO containing 20% PBS buffer is used as Probe 2 for the selective turn-off detection of vanillin. The green fluorescence emission of Probe 2 at 500 nm is selectively quenched by vanillin with a detection limit of 0.8 μM. Finally, the analytical novelty of the developed probes was examined by quantifying ortho-vanillin and vanillin in spiked food samples with good recovery percentages.

3-Hydroxy-2-naphthohydrazide:用于正香兰素和香兰素荧光传感的市售化合物。
香兰素和邻香兰素是食品工业中大规模使用的最重要的调味添加剂。本文探讨了市售 3-hydroxy-2-naphthohydrazide (3HN) 的聚集诱导发射(AIE)行为,并将其应用于香兰素和邻香兰素的检测。随着二甲基亚砜中 HEPES 或 PBS 缓冲液(pH 7.4)馏分的增加,二甲基亚砜中弱荧光的 3HN 在 500 纳米处的荧光增强。含有 30% HEPES 缓冲液的 DMSO 中的 3HN 被用作探针 1,用于选择性检测原香兰素。探针 1 在 415 纳米波长处对原香兰素显示出新的荧光发射,而不会改变探针在 500 纳米波长处的发射。探针 1 具有很高的特异性,可以检测低至 0.3 μM 的原香兰素。相反,3HN 在含有 20% PBS 缓冲液的 DMSO 中用作探针 2,可选择性地检测香兰素。探针 2 在 500 纳米波长处发出的绿色荧光会被香兰素选择性淬灭,检测限为 0.8 μM。最后,通过对食品样品中的原香兰素和香兰素进行定量分析,检验了所开发探针的分析新颖性,其回收率很高。

期刊介绍: Luminescence provides a forum for the publication of original scientific papers, short communications, technical notes and reviews on fundamental and applied aspects of all forms of luminescence, including bioluminescence, chemiluminescence, electrochemiluminescence, sonoluminescence, triboluminescence, fluorescence, time-resolved fluorescence and phosphorescence. Luminescence publishes papers on assays and analytical methods, instrumentation, mechanistic and synthetic studies, basic biology and chemistry. Luminescence also publishes details of forthcoming meetings, information on new products, and book reviews. A special feature of the Journal is surveys of the recent literature on selected topics in luminescence.
