A Micelle-Based Chemosensing Ensemble for the Fluorimetric Detection of Chloride in Water

Caught in a trap! Fluorimetric chloride sensing in water is achieved by exploiting the changes in partition constant of a receptor complex in its bound and unbound states. In the presence of chloride, the complex preferentially resides in the micelle pseudo phase, where its contact with a fluorescent dye results in pronounced quenching effects (see figure).
