本文研究了在金属配位中广泛应用的一类典型配体--简单易制的salen的阴离子结合和传感亲合力。结果表明，Salophen对氟离子具有比色和荧光选择性化学传感器作用，其作用机制是通过阴离子诱导的构象变化和随后的激发态分子内质子转移（ESPT）过程实现的。F（-）诱导的快速响应以及明显的光学变化表明，阴离子传感机制可能有助于设计和合成新的F（-）优先选择性探针。
In this paper, anion binding and sensing affinity of the simple and easy-to-make salen, a typical class of ligand used comprehensively in metal coordination, was investigated. Results indicated that salophen was both a colorimetric and fluorescent selective chemosensor for fluoride ion, which operated by the anion-induced conformational changes and subsequently excited-state intramolecular proton transfer (ESPT) process. The F(-)-induced quick response, as well as noticeable optical changes, suggested that anion-sensing mechanism maybe help to design and to synthesize the new preferential selective probes for F(-).
