摘　　要：通过Suzuki聚合反应合成了一种新型的含磷光单元的主链型聚芴类聚合物,对其进行了表征分析,并且研究了其在薄膜状态下的光学性质.在以这种聚合物作为电致发光器件的发光层时,用高功函数金属铝(Al)作为器件阴极时可以获得和用低功函数金属钡(Ba)作为阴极时相当的器件性能.A series of novel polyfluorene containing iridium complex in the main chains were synthesized and characterized. The photoluminescent properties of these polymers in thin film were investigated. Electroluminescent devices fabricated by using these polymers as the emissive layer with high work-function metal such as Al showed similar good device performances which can be obtained typically only with low work-function metal, such as Ba or Ca as cathodes .
