Abstract
Aluminum (III) tris[2-(2-hydroxyphenyl)-5-phenyl-1,3-oxazole] (Alppo3), has been synthesized as a new efficient blue electroluminescent (EL) material. Alppo3 provided good color purity, high luminance, and high efficiency of blue light-emission in an organic light-emitting device. The EL maximum wavelength is 420 nm and Commission Internationale de l'Eclairage coordinates are x=0.16, y=0.15 of blue color chromaticity. The luminance efficiency and the maximum luminance of Alppo3 device were 3 lm/W at 6.05 mA/cm2 (345 cd/m2) and 13,900 cd/m2, respectively.
