A series of new tetraphenylethylene monomer, dimer and three-dimensional trimer based triptycene-bridged triphenylethenes has been constructed. Their structures were clearly confirmed and the irregular fluorescent behaviors at different temperatures and solvents were investigated. Results showed the new tetraphenylethylenes performed remarkable aggregation-induced emission (AIE) properties and the emission intensities are dependent on temperature and viscosity. Compared with the model tetraphenylethylene without connecting triphenylethylene, the fluorescence quantum yields of the titled triptycene-scaffolded tetraphenylethylenes in aggregation are greater than tetraphenylethylene and increased as the increasing of the triphenylethylene units.

一系列新的四苯乙烯单体，二聚体和三维三聚体桥联的三苯撑三苯乙烯已被构建。明确确认了它们的结构，并研究了在不同温度和溶剂下的不规则荧光行为。结果表明，新的四苯基乙烯具有显着的聚集诱导发射（AIE）性能，并且发射强度取决于温度和粘度。与没有连接三苯乙烯的模型四苯乙烯相比，标题三萜骨架的四苯乙烯的聚集体的荧光量子产率大于四苯乙烯，并且随着三苯乙烯单元的增加而增加。
