摘要: A new fluorene-co-carbazole-based copolymer (PFCD), with a bulky peripheral dendritic carbazole pendant at the 9-position, has been designed and synthesized through Suzuki polycondensation reaction. The resulting exhibits desirable properties, such as excellent solubility, good thermal stability, electrochemical properties. PFCD also shows efficient blue light-emitting properties color purity high photoluminescent quantum yield. results of photo-physical indicate that large side dendron groups can not only efficiently suppress π-stacking polymer chains but raise HOMO level material. Thus, is expected to be promising pure material further experiments on electroluminescent film morphology, aggregation behaviors are in progress.
