- Abstract
- We have synthesized and characterized new blue host materials for OLEDs; 9,10-di-o-tolylanthracene (1), 2-tert-butyl-9,10-diphenylanthracene (2), 10,10'-diphenyl-9,9'-bianthracene (3), and 1,4-bis(10-phenylanthracen-9-yl)benzene (4). To explore electroluminescent properties of these materials, multilayered OLEDs with the configuration of ITO/NPB (50 nm)/Blue emitters (1-4) (30 nm)/Liq (2 nm)/Al (100 nm) were fabricated. Among those non-doped devices, the device 4a employing 4 as an emitter showed high efficiencies of 4.11 cd/A, 3.31 lm/W, and 2.35%, respectively. The device 2b employing 2 as host material for PFVtPh blue dopant material exhibited excellent efficiencies with 5.64 cd/A, 4.14 lm/W, and 4.54%.
