- Abstract
- A red fluorescent material 4-(1,3-Indanedione-2-yl)-2-(adaman-1-yl)-6-(10-aza-2,3,4,5,6,7-hexahydronaphtio[1,8-gh]chromen-10(1H)-one-9-enyl)-4H-pyran is synthesized and characterized. In this material, four methyl groups and adamantly group are introduced into DCJTB skeleton to increase steric hindrance between red emitters in the emitting layer of devices and thus improve the EL efficiencies by preventing concentration quenching. In particular, a device doped with this material in the emitting layer exhibits the luminous and power efficiencies of 3.58 cd/A and 1.61 lm/W at 20 mA/cm(2), respectively. The CIE coordinates of this device was (0.64, 0.35) at 7.0V.
