通过化学方法将苯并咪唑基铱配合物连接到聚（3，6-咔唑）侧链上，成功开发出线性发绿色光的电致磷光聚合物。获得高达33.9 cd A（-1）的效率值，表明在不存在包封效应的情况下的线性结构也可以导致与树枝状聚合物或超支化聚合物相当的器件性能。
Linear green light-emitting electro-phosphorescent polymers have been successfully developed by chemically attaching a benzoimidazole-based iridium complex to the side chain of poly(3,6-carbazole). Efficiency values as high as 33.9 cd A(-1) are obtained, indicating that the linear structure in the absence of an encapsulation effect can also lead to a device performance that is comparable with that of either dendrimer or hyperbranched polymers.
