A new class of carbazole derivatives was facilely synthesized by Wittig–Horner and Suzuki reactions, and their thermal and photophysical properties were investigated. They exhibited aggregation-induced emission enhancement (AIEE) characteristics and high thermal stability. The glass transition temperatures (Tg) of these compounds ranged from 178 to 231 °C, while their decomposition temperatures (Td) ranged from 496 to 535 °C. The solubility of the derivatives did not monotonically change with an increasing number of phenylene bridges, but exhibited a clear odd-even effect.
