Abstract
In this study, we synthesized and characterized two novel deep blue emitting materials based on indenoquinoline-substituted phenylanthracene derivatives. Multilayer organic light-emitting diodes were fabricated with the following sequence: indium-tin-oxide (ITO)/4,4′,4″-tris[2-naphthyl(phenyl)amino
(2-TNATA)/4,4′-bis(N-N-naphthyl)-N-phenylamino) biphenyl (NPB)/Blue emitting material (1 or 2)/Bathophenanthroline (Bphen)/lithium quinolate (Liq)/Al. A device B using ‘7,7-dimethyl-9-(10-phenylanthracen-9-yl)-7H-indeno[1,2-f] isoquinoline
(2)’ as an emitter showed the efficient emission with the luminous efficiency, power efficiency, and external quantum efficiency of 2.30 cd/A, 1.02 lm/W, 2.94% at 20 mA/cm2, respectively. This device exhibited deep-blue emission with the Commission Internationale De
LÉnclairage (CIE) coordinates of (0.16, 0.08) and λmax = 436 nm at 8.0 V.
