Efficient fluorescent chemosensors for HSO_4- based on a strategy of anion-induced rotation-displaced H-aggregatest

摘要

A novel fluorometric sensing strategy based on the anion-induced rotation-displaced H-aggregates of styrytindolium dyes was employed to enhance the selectivity of fluorescent chemosensors for HSO_4 detection. The marvelous anion-induced H-aggregate strategy opens new routes to simple synthesis of receptors for tetrahedral anionic species.
