摘　　要：以4-氯-7-硝基苯并呋咱(NBD-Cl)和咪唑-4-甲醛为原料,设计合成了一种用于检测亚硫酸氢根离子(HSO-3)的荧光探针,并通过核磁共振氢谱(1H-NMR)、质谱(MS)对其结构进行了表征.荧光测试结果表明:在二甲基亚砜(DMSO)水溶液中,该化合物能够对HSO-3表现出荧光增强响应,而相同条件下该化合物对其他阴离子几乎没有类似的荧光识别现象,因此该荧光化合物对HSO-3具有专一荧光识别作用,是一种有效的HSO-3荧光探针.A fluorescent probe for the detection of bisulfite(HSO-3)was designed and synthesized using 4-chloro-7-nitrobenzofurazan(NBD-Cl)and imidazole-4-carbaldehyde.Its structure was characterized with 1H-NMR and MS.The fluorescence test results showed that the compound exhibited a fluorescence-enhancing response to HSO-3 in aqueous solution of dimethyl sulfoxide(DMSO),but other anions had almost no similar fluorescence recognition for the compound under the same conditions.Therefore the fluorescent compound has a specific fluorescence recognition effect on HSO-3 and is an effective HSO-3 fluorescent probe.
