合成了一种新型的,能在含水介质中比色荧光双通道单一选择性识别CN-的传感器分子1-羟基萘甲叉酰肼乙基-3-羟基萘甲叉酰肼甲基苯并咪唑溴鎓盐(J1).在J1的DMSO/H2O(体积比3∶2)HEPES的缓冲体系(pH=7.2)中分别加入F-、Cl-、Br-、I-、AcO-、HSO-4、ClO-4、H2pO-4-、SCN-和CN-等阴离子后,只有CN-的加入会使得溶液颜色发生明显的变化,由无色变为深黄色.相应地在J1的DMSO/H2O(体积比4∶1)HEPES的缓冲体系(pH=7.2)中加入CN-,溶液发出明亮的黄色荧光.这一识别过程,不会受到其它阴离子的干扰.紫外-可见光谱的最低检测限为1.57×10-7mol/L,检测线性范围为3.875×10-4～2.15×10-2 mol/L.荧光光谱的最低检测限为4.63×10-6mol/L,检测线性范围为0.8 ×10-4～1.60×10-3mol/L.此结果表明,J1是一种良好的用于识别CN-的化学传感器,在含水介质中对CN-具有选择性好、灵敏度高以及抗干扰性强的识别性能.与此同时,基于J1对于CN-的高选择性识别我们制备了CN-的检测试纸,该试纸能够方便、快捷、准确地检测水中的CN-.
