Chem Commun (Camb). 2012 Mar 11;48(21):2695-7. doi: 10.1039/c2cc17515k. Epub 2012 Feb 03.

The peripheral triphenylamine-encapsulated red-emitting iridium(III) complexes have been designed and synthesized. External quantum efficiency over 15% has been realized in single-layer polymer light-emitting diodes, which is the highest ever reported for solution-processed red phosphorescence.

Ligand-metal cooperation in iridium and platinum complexes bearing tricyclic dibenzobarrelene-based PC(sp(3))P pincer ligands is discussed. We demonstrated that the carbon-metal bond in these complexes may be efficiently cleaved and regenerated via 1,2-addition/elimination reactions.
