Highly Efficient Blue Organic-Light Emitting Diodes Based on 9,10-Diphenylanthracene End-Capped 5H-Pyrido[3,2-b]Indole Groups

초록

In this study, two blue emitters based on 9,10-diphenylanthracene and 5H-pyrido[3,2-b]indole were designed and synthesized for OLEDs. Among those, a device using 5-(9,10-diphenyl-2-(5H-pyrido[3,2-b]indol-5-yl)anthracen-6-yl)-5H-pyrido[3,2-b]indole(2) exhibited efficient blue emission with a luminous, power and external quantum efficiency of 5.99 cd/A, 2.70 lm/W and 3.94% at 20 mA/cm(2), respectively. The CIE coordinates of this device were (x = 0.15, y = 0.21) at 6.0 V.
