Abstract:
In this study, we designed and synthesized emitting materials based on naphthoanthracene derivatives. Organic Light Emitting-Diodes (OLEDs) devices using each four materials were fabricated. All devices showed efficient emissions. In particular, a device using 1-(5,5-Dimethyl-9-phenyl-[5H-naphth[3,2,1-de]anthracen-3-yl])-1H-indole as an emitter at 20 mA/cm2 exhibited luminous efficiency, power efficiency, and external quantum efficiency of 6.51 cd/A, 4.19 lm/W, and 2.48%, respectively, with Commission Internationale d'Énclairage (CIE) coordinates of (0.19, 0.49) at 7.0 V.
