摘要
聚集诱导发光(aggregation-induced emission,AIE)化合物因在生物和化学传感、发光材料、显示等领域具有重要价值而备受关注.作为一类重要的功能分子,有机氟化合物在化学和材料等领域被广泛研究.汇总了具有聚集诱导发光性质的有机氟化合物,并进行了分类讨论.AIE有机氟化合物包括氟代的四苯基乙烯(TPE)衍生物、二苯乙烯基蒽(DSA)衍生物、氰基二苯基乙烯衍生物和二苯乙烯基苯衍生物等常见的AIE化合物,也包括聚合物、碳硼烷簇合物和室温磷光化合物,还有其它一些含氟结构.AIE化合物氟代后,稳定性一般会提高,氟原子参与分子间相互作用,导致聚集态的结构发生改变,从而导致发光性质的改变,如发光增强、发光波长红移(蓝移)或发光量子效率及发光寿命提高等.最后,对AIE有机氟化合物的研究前景进行了展望.
Aggregation-induced emission(AIE)compounds have attracted much attention due to their important potential applications in biological and chemical sensing,luminescent materials,display and other areas.As an important class of functional molecules,organofluorine compounds have been widely studied in areas such as organic chemitry and materials chemistry.The organofluorine compounds with AIE properties are summarized and classified.The currently reported AIE organofluorine compounds include the fluorinated tetraphenylethene(TPE)derivatives,9,10-distyrylanthracene(DSA)derivatives,cyanostilbene derivatives,distyrylbenzene derivatives,fluorinated polymers,carborane clusters,room temperature phosphorescent molecules,and some other fluorinated structures.With fluorine atoms in the structures,the stability of the resulting AIE compounds is generally improved,and fluorine atoms often participate in the intermolecular interactions leading to significant changes in the structure of the aggregation state,and hence changes in luminescence properties,for example,emission enhancement,bathochromism or hypsochromism of the emissions,improvement of the emission quantum yield and lifetime.The prospects of the future study are also discussed.
