A series of new aggregation-induced emission compounds with strong blue light-emitting properties derived from triphenylethylene were facilely synthesized by a Wittig–Horner reaction of bis(4-bromophenyl)methanone with diethyl 4-bromobenzylphosphonate, followed by a Suzuki reaction with arylboronic acids. Their maximum fluorescence emission wavelengths were 452–462 nm. The glass transition temperatures ranged from 70–145 °C, and the decomposition temperatures were 360–508 °C. The unoptimized device fabricated with benzofuranyl substituted compound as emitter turned on at ∼6 V, and the maximum luminance was ∼1500 cd m−2.
通过双(4-溴苯基)甲酮与4-溴苄基膦酸二乙酯的Wittig-Horner反应,然后与芳基硼酸进行Suzuki反应,轻松合成了一系列源自三苯乙烯的具有强蓝光发射特性的新型聚集诱导发光化合物。它们的最大荧光发射波长为 452–462 nm。玻璃化转变温度范围为70-145°C,分解温度为360-508°C。使用苯并呋喃基取代的化合物作为发射极制造的未经优化的器件在〜6 V时开启,最大亮度为〜1500 cd m−2。
