Abstract

Blue fluorescent materials based on 9,9'-diethyl-2-diphenylaminofluorene derivatives were synthesized and characterized. These materials were used as the blue dopant materials for the emitting layer of organic light-emitting diode devices with the following device structure: ITO/DNTPD (40 nm)/NPB (20 nm)/MADN: dopants (2%, 20 nm)/$Alq_3$ (40 nm)/Liq (1.0 nm)/Al. All devices exhibited highly efficient blue emission. One of these devices exhibited a maximum luminance, luminous efficiency, power efficiency and CIE x, y coordinates of 8400 $cd/m^2$, 8.10 cd/A at 20 $mA/cm^2$, 3.36 lm/W at 20 $mA/cm^2$ and (0.151, 0.159), respectively. A deep blue device with CIE coordinates of (0.152, 0.139) showed the maximum luminance, luminous efficiency and power efficiency of 8630 $cd/m^2$, 6.31 cd/A at 20$mA/cm^2$ and 2.62 lm/W at 20 $mA/cm^2$, respectively.
