Photoluminescent substances have many applications including dopants for organic light-emitting diodes (OLEDs), luminescent bio-labeling reagents, photocatalysts and chemosensors for oxygen. Cyclometalated Ir(III) complexes are particularly interesting in this capacity as they have high photochemical stability, high quantum efficiencies and a broad range of emission properties that allow their luminescence to span from near infra-red to blue light. Yanfang Li, Yang Liu and Ming Zhou prepare and characterize a dendritic FRET donor–acceptor system with cationic Ir(III) complex core in their Hot Article in Dalton Transactions. Their biocompatible system displays efficient photoluminescence of the Ir(III) complexes via a FRET pathway and the luminophore core is protected from quenching by molecular oxygen under the photo excitation.
