一种同时含有溴和甲酰基的芴衍生物在室温下在普通有机溶剂中表现出明亮的磷光发射。在298 K氯仿溶液中，绝对磷光量子产率达到5.9%.当将芴衍生物掺入到聚（甲基丙烯酸甲酯）膜中时，即使在空气中在室温下持续5天以上也类似地观察到磷光发射。
A fluorene derivative having both bromo and formyl groups exhibited bright phosphorescence emission in common organic solvents at room temperature. The absolute phosphorescence quantum yield reached 5.9% in chloroform at 298 K. When the fluorene derivative was incorporated into a poly(methyl methacrylate) film, the phosphorescence emission was similarly observed even under air at room temperature for over five days.
