Abstract

A couple of new fluorescent probes, based on diethoxycarbonyl glycoluril, were synthesized and characterized by (1)H NMR, X-ray crystal structure. The probes were found to be relatively highly fluorescence with quantum yields of 0.20 and 0.18, respectively, at room temperature in THF solution. Both of the proposed probes were tested using different phenolic compounds, showing very high selectivity and sensitivity for 2-nitrophenol by forming a 1:1 complex in THF-MeOH (9:1, v/v). Additionally, the sensors could be used for the qualitative analysis of 2-nitrophenol in real water samples.

摘要

基于二乙氧羰基甘脲的两种新型荧光探针已被合成并通过 1H NMR 和 X 射线晶体结构进行了表征。在室温下，探针在四氢呋喃溶液中的量子产率分别为 0.20 和 0.18，具有较高的荧光性。使用不同的酚类化合物对这两种探针进行了测试，结果表明它们在 THF-MeOH（9:1，v/v）中形成 1:1 络合物，对 2-硝基苯酚具有很高的选择性和灵敏度。此外，这些传感器可用于实际水样中 2-硝基苯酚的定性分析。
