The development of new optical anion chemosensors with high sensitivity and selectivity is very important, since anions possess some fundamental roles in a wide range of biological and chemical processes. The displacement approach is a method using anion binding sites and signaling subunits, which are not covalently attached but forming a coordination complex, in which the presence of anions revives the noncoordinated spectroscopic behavior of the indicator. In the past five years, according to the displacement strategy, many good optical anion chemosensors have been successfully obtained. This paper reviews the recent progress in the field of the fluorescent and colorimetric anion chemosensors designed according to the displacement strategy (mainly from 2008 to 2011), and gives some outlooks for the further exploration of new optical anion chemosensors.
新型光学阴离子传感器的发展具有高灵敏度和选择性非常重要，因为阴离子在广泛的生物和化学过程中具有一些基本作用。取代法是一种使用阴离子结合位点和信号亚基的方法，它们不是通过共价键连接的，而是形成配位复合物，其中阴离子的存在恢复了指示剂的非配位光谱行为。在过去的五年中，根据取代策略，已经成功地获得了许多良好的光学阴离子传感器。本文综述了根据取代策略设计的荧光和比色阴离子传感器领域的最新进展（主要是 2008 年至 2011 年），并对进一步探索新型光学阴离子传感器进行了展望。
