Two phosphorescent iridium(III) complexes Ir(DFPP) 2 (acac) and Ir(DFPP) 2 (pic) (DFPP, 2-(2,4-difluorodephenyl)-3-phenylpyridine; acac, acetylacetone; pic, 2-picolinic acid) were synthesized. The complexes have strong phosphorescent characters. The organic light emitting devices (OLEDs) based on these complexes with the configuration of ITO/NPB (40nm)/Ir complex: CBP (7%, 30nm)/BCP...
Two red emitting iridium complexes (DBA) 2 Ir(acac) and (BA) 2 Ir(acac) (DBA=5,6-dihydro-benzo[c]acridine, BA=benzo[c]acridine, acac=acetylacetone) were synthesized. Organic light-emitting devices using these complexes as dopant emitters have been fabricated. The results showed that these complexes have strong phosphorescent characters and the devices emit pure red light. The maximum...
