The one-pot synthesis of homoleptic phenylphthalazine iridium(III) complexes and their application in high efficiency OLEDs
A series of homoleptic cyclometalated iridium (III) complexes bearing a 1-phenylphthalazine framework have been synthesized with a facile one-pot method and characterized by X-ray single crystal diffraction. All complexes exhibited orange or red emission peaks at 583?623 nm with short lifetimes of 1.3?2.6 mus and high photoluminescence quantum yields of 41%?82%. These complexes exhibit good thermal stability with high Td of 275?394 C. The electronic states and orbital distributions of these iridium (III) complexes were studied by density functional theory. These complexes were used as emissive materials in Organic light-emitting diodes (OLEDs). The device based on 2 gave a peak current efficiency and external quantum efficiency (EQE) of 35.1 cd A?1 and 21.2%, respectively. The color coordinates of device based on 3 fully meet that of standard red of the National Television Standards Committee (NTSC). These results suggest that homoleptic phenylphthalazine iridium (III) complexes have potential application as efficient emitters in OLEDs.
