英文摘要： The electrochemical polymerization is used to prepare the novel AIE(Aggregation-Induced Emission) materials with high thermal stability. The organic fluorescent molecule with the AIE properties which can be polymerized by electrochemical polymerization is designed and synthetized. The polymer film is synthetized by one step of electrochemical polymerization. AIE polymer film has the dual characteristics of small molecules and polymer fluorescent material.The morphology and luminescence efficiency of the polymer film is control by changing the electrolyte composition, electrochemical methods and polymerization parameters such as power. The key technology of the synthesis of AIE polymer films by in situ electrochemical polymerization will be got in this project. The AIE polymer film with high fluorescence efficiency and smooth surface morphology will be used to the production of organic electroluminescent devices. This study will get a simple, efficient and new method of preparing high-performance AIE polymer film, the polymerization mechanism, AIE theories and morphological control factors of the polymer, which will be contributing to the development of light-emitting materials of organic light-emitting diode(OLED) and OLED industrial.
