Compounds comprising a ligand having a quinoline or isoquinoline moiety and a phenyl moiety, e.g., (iso)pq ligands. In particular, the ligand is further substituted with electron donating groups. The compounds may be used in organic light emitting devices, particularly devices with emission in the deep red part of the visible spectrum, to provide devices having improved properties.

A simple, practical iron salt catalyzed procedure allows fast cross-couplings of N-heterocyclic chlorides and bromides with various electron-rich and -poor arylmagnesium reagents. A solvent mixture of THF and tBuOMe is found to be essential for achieving high yields mainly by avoiding homocoupling side reactions.

respectively. Ionic complexes are conducive to the efficient solution-processed phosphorescent red organic light-emitting diodes (OLEDs). Among the three devices, the Ir2-based device achieved a relatively high external quantumefficiency, current efficiency, and power efficiency of 1.12 %, 0.75 cd/A, and 0.37 lm/W, respectively. These results indicated that polymethoxy-based ionic Ir(III) complexes have great
