Molecular Engineering of Iridium Blue Emitters Using Aryl N‐Heterocyclic Carbene Ligands
The synthesis of a new series of neutral bis[2-(2,4-difluorophen-2-yl)pyridine][1-(2-aryl)-3-methylimidazol-2-ylidene]iridium(III) complexes is reported. Each complex has been characterized by NMR spectroscopy, UV/Vis spectrophotometry, and cyclic voltammetry, and the photophysical properties examined in depth. Furthermore, two of the complexes have been characterized by single-crystal X-ray diffraction analysis. By systematically modifying the cyclometalating aryl group on the N-heterocyclic carbene (NHC) ligand from 2,4-dimethoxyphenyl to 6-methoxy-2-methyl-3-pyridyl, the energy levels of the Ir complexes were modified to produce new blue emitters with increased HOMO and triplet-state ene…
Bis(arylimidazole) Iridium Picolinate Emitters and Preferential Dipole Orientation in Films
The straightforward synthesis and photophysical properties of a new series of heteroleptic iridium(III) bis(2-arylimidazole) picolinate complexes are reported. Each complex has been characterized by nuclear magnetic resonance, UV-vis, cyclic voltammetry, and photoluminescent angle dependency, and the emissive properties of each are described. The preferred orientation of transition dipoles in emitter/host thin films indicated more preferred orientation than homoleptic complex Ir(ppy)3.
