  调节共轭刚性平面结构以实现荧光识别特性的转变

  摘要：

  双苯并咪唑是一类重要的荧光分子探针材料，在环境、临床和生物系统中都有应用。此外，不同的双苯并咪唑衍生物由于具有优异的配位特性和荧光特性，被广泛研究用于阳离子识别。在本研究中，探讨了三种双苯并咪唑衍生物（B 1、B 2和B 3）与苯基共轭体系的增加和用于检测有毒重金属离子（如 Hg 2+ ）的荧光传感特性之间的关系。并进行了分析。B 1包含一个没有附加物的双苯并咪唑单元，而B 2和B 3在两个苯并咪唑环之间具有不同的苯基附属物；随着共轭体系的扩展，阳离子识别的选择性增加，但稳定性显着降低。同时，通过荧光光谱、1 H NMR光谱、ICP分析和DFT计算等方法研究了它们对Hg 2+的检测限（LOD）和识别机制。令人鼓舞的是，B 2表现出较高的吸附和分离效率，为汞离子吸附/去除材料的开发提供了参考。
