摘要:

分别以间苯二酚和4-氯间苯二酚为原料，合成了两种新型香豆素类亚硫酸氢根离子探针4-甲基-8-甲酰基-7-羟基香豆素和4-甲基-8-甲酰基-7-羟基-6-氯香豆素，其结构用IR，1H NMR，MS等方法进行了表征。研究了该亚硫酸氢根离子探针的检测机理、选择性、方法的分析特性及其在实际样品检测中的应用，建立了一种在水溶液中检测亚硫酸氢根离子的荧光分析方法。

Abstract:

Two novel coumarin-based bisulfite anion probes, 4-Methyl-8-formyl-7-hydroxylcoumarin and 4-methyl-8-formyl-7-hydroxyl-6-chlorocoumarin, were synthesized by using resorcinol and 4-chloro resorcinol as the raw material respectively. The structures of the probes were characterized by IR, 1H NMR and MS. The mechanism of determination, selectivity to bisulfite anion, analytic method and the application in the actual samples of the probes were investigated. A fluorescence analytic method for detection of bisulfite anions in water was established.
