Luminescence of triarylphosphines and their application to detection of elemental chlorine in aqueous solution†
Abstract
The concept of aggregation induced emission has been utilized to raise luminescence of triarylphosphines for the first time. Appreciable emission in the aggregated state as well as the Lewis basic character of these compounds were capitalized upon to demonstrate the functional utility as fluorescent chemosensors for elemental chlorine, Cl2, in aqueous solution.
