合成了一类新的含三芳胺和二咔唑基三苯乙烯结构的化合物，该化合物具有高的热稳定性和聚集诱导发光增强性能。3B-TPA的玻璃化转变温度和5%失重温度分别高达214.3 °C和516.8 °C。该化合物具有明显的光诱导分子内电荷转移特性。聚集体的存在显著影响了π-π* 跃迁，使π-π* 吸收峰红移6-7 nm。这些化合物在聚集状态下可以发出强烈的蓝绿光。
A new class of compounds containing triarylamine and dicarbazolyl triphenylethylene moieties with high thermal stability and aggregation-induced emission enhancement properties was synthesized. The glass transition temperature and 5% weight loss temperature of 3B-TPA are up to 214.3 °C and 516.8 °C, respectively. The compounds exhibited significant photoinduced intramolecular charge-transfer properties. The aggregation considerably affected the π–π* transition and resulted in 6–7 nm red shift of the π–π* absorption wavelength at the peak in UV-vis spectra. The compounds could emit intense blue-green light in aggregated states.
