Advances in Fluorinated Organometallic Complexes with Aggregation-Induced Emission Characteristics

In recent years,the compounds with aggregation-induced emission(AIE)characteristics have received increasing attention because they exhibit much higher luminescence quantum yields in aggregation or solid states than in solution.Due to the presence of the fluorine atom(s),fluorinated functional compounds generally have unique structures,and physical,chemical and biological properties.Herein,the luminescent organometallic complexes with AIE characteristics having fluorine-containing ligands are summarized,according to the types of central metal atoms and ligands.Such organometallic complexes are mainly those of iridium,platinum and gold,with potential applications in light-emitting devices,chemical sensing,cell imaging and data storage,etc.The prospects of the relevant studies are also discussed.
