重金属阳离子荧光传感器合成及光谱性研究

【摘要】 通过亚胺缩合的反应制备出阳离子荧光传感器(Cation Fluorescent Sensors,CFSs),并对其结构、光谱性能检测、荧光量子产率等进行了详细的研究。通过荧光化学传感器产生的荧光光谱一直是高效的分析方法,因此合成了新的基于席夫碱的荧光化学传感器,并研究了对各种金属离子的结合特性。在CH3CN溶液中测试了阳离子荧光传感器对不同阳离子的选择性响应,发现对Cu2+有较好的选择性,可用于Cu2+的检测。该类阳离子荧光传感器是基于2,2-联噻吩-5-乙醛的荧光发射基团和邻氨基苯甲醚为识别基团的一类阳离子荧光传感器。更多还原

【Abstract】 This article was prepared by reaction of imine condensation out of the cationic fluorescent sensor(Cation Fluorescent Sensors,CFSs). And CFSs structure, spectral performance testing, fluorescence quantum yield were studied in detail. With this regard, fluorescent chemosensors have been of particular interest, as fluorescence spectroscopy has turned to be one of the most effective and reliable analytical methods. So we synthesized new kinds of fluorescent sensors based on Schiff base, and investigated its binding properties toward various metal ions. In CH3 CN solution tested CFSs selective response to different cations, Cu2+was found to have good selectivity, can be used for the detection of Cu2+. This class is based on cationic fluorescent sensor 2,2-bithiophene-5-carbaldehyde fluorescence emission groups and 2-methoxyaniline as a class of cationic fluorescent sensors to identify groups.更多还原
