通过将蓝色、绿色和红色掺杂单元作为单独的发光物种共价连接到作为单独的聚合物主体的聚芴的侧链上，开发了具有高电致发光效率和优异的显色指数（CRI）值的白色电致发光单一聚合物体系。其单层器件的发光效率为8.6 cd A（-1），CIE坐标为（0.33，0.36），CRI值为88。
A white electroluminescent single polymer system with both high electroluminescence efficiency and excellent color rendering index (CRI) value is developed by covalently attaching blue, green, and red dopant units as individual light-emitting species to the side chain of polyfluorene as individual polymer host. A luminous efficiency of 8.6 cd A(-1), CIE coordinates of (0.33, 0.36) and CRI value of 88 was demonstrated with their single-layer devices.
