We synthesized a new cyanide (CN−) chemosensor CX based on a nucleophilic addition reaction prompted by cyanide ion, which could be used for highly selective and sensitive fluorescence turn‐on detection of cyanide in aqueous media. The CX showed selective fluorescence recognition for CN−, the miscellaneous competitive anions (F−, Cl−, Br−, I−, AcO−, H2PO4−, HSO4−, ClO4−, S2−, PO43−, CO32− and SCN−)
我们合成了新的氰化物(CN - )化学传感器CX基于亲核加成反应提示由氰化物离子,其可用于高选择性和灵敏的荧光接通在含水介质中检测氰化物。在CX表明选择性荧光识别为CN - ,杂有竞争力的阴离子(F - ,氯- ,溴- ,我-,ACO -,H 2 PO 4 -,HSO 4 -,CLO 4 -,S 2 -,PO 4 3-,CO3 2 -和SCN - )并没有导致任何显著的干扰。朝向CN的传感器的检测极限-是1.15×10 -7摩尔•L -1。该传感器已成功应用于估计樱桃种子中的氰化物离子。基于测试条CX被制造,这可以被用作方便和有效的CN -试验试剂盒检测CN -在为“在最字段”测量水溶液。
