A halogen ion-selective phosphorescence turn-on probe based on induction of Pt–Pt interactions†
Abstract
Square-planar cyclometalated platinum(II) complexes have been found to serve as turn-on phosphorescent probes selectively for biological halogen ions. This is based on the halogen ion induced self-assembly of Pt(II) compounds in aqueous media, resulting in intermolecular Pt–Pt interaction associated emission.
