合成了几种基于二乙氧基羰基甘脲的新型荧光探针,并通过1H NMR、X射线晶体结构进行了表征。发现探针在室温下的 THF 溶液中具有相对较高的荧光性,量子产率分别为 0.20 和 0.18。两种拟议的探针均使用不同的酚类化合物进行了测试,通过在 THF-MeOH(9:1,v/v)中形成 1:1 复合物,显示出对 2-硝基苯酚的极高选择性和灵敏度。此外,该传感器还可用于实际水样中 2-硝基苯酚的定性分析。
A couple of new fluorescent probes, based on diethoxycarbonyl glycoluril, were synthesized and characterized by1H 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.
