摘要：
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 469-493 nm in solid states. The glass transition temperatures range from 138 to 180 degrees C and the decomposition temperatures are 495-557 degrees C. The unoptimized device fabricated with the triphenylethene compound combined with three tetraphenylethene groups as emitters turns on at similar to 6 V and the maximum luminance is observed at similar to 1908 cd/m(2) and 15.5 V. The electroluminescence peak of the device is at 474 nm and the Commission Internationale de PEclairage (CIE) chromaticity coordinate values are (0.18, 0.31) at 10 V.
