文摘
Aggregation-induced emission compounds containing triphenylethene and tetraphenylethene moieties with high thermal stability and good device properties have been synthesized. Their maximum fluorescence emission wavelengths are 469鈥?93 nm in solid states. The glass transition temperatures range from 138 to 180 掳C and the decomposition temperatures are 495鈥?57 掳C. The unoptimized device fabricated with the triphenylethene compound combined with three tetraphenylethene groups as emitters turns on at 6 V and the maximum luminance is observed at 1908 cd/m2 and 15.5 V. The electroluminescence peak of the device is at 474 nm and the Commission Internationale de l鈥橢clairage (CIE) chromaticity coordinate values are (0.18, 0.31) at 10 V.
