Electrochemical Polymerization of Carbazolyl Triphenyl Ethylene and Its Properties

对具有明显聚集诱导发光性能(AIE)的化合物4,4'-双(2,2'-双(4-(6-(9H-咔唑基)己氧基)苯基)乙烯基)联苯(p2bc6)以电化学聚合法制备了聚合物发光薄膜.该聚合薄膜的结构、光学性能和表面形貌通过红外光谱、紫外光谱(UV)、荧光光谱和原子力显微镜表征.结果表明:聚合前体通过分子中咔唑基团聚合形成聚合物薄膜;薄膜具有良好的发光性质;制得的电化学聚合薄膜表面平整,表面粗糙度可达到3 nm以下,有望作为发光材料应用于PLED器件中.

A compound （ p2bc6） which shows a significant aggregation-induced emission phenomenon was used to make polymers by electrochemical polymerization.The structures, optical performance and surface morphology of the electrochemical polymerized films were characterized by means of infrared spectroscopy, near ultra violet（ UV） , photoluminescence measurements and atomic force microscopy.The results showed that the electrochemical poly-merization proceeded from carbazole groups, the film emitted fluorescence and had flat surface which the root mean square （ rms） of surface roughnesses was less than 3 nm.It is suggested that they are potential materials for fabrica-tion in PLED devices.
