摘要：

We report the first synthesis of a series of novel conjugated copolymers derived from 9,9-dioctylfluorene (DOF) and 2,1,3-benzoselenadiazole (BSeD) synthesized by palladium-catalyzed Suzuki coupling reaction. The comonomer ratios (DOF:BSeD) were 98:2, 85:15, and 50:50 respectively. The copolymers were soluble in common organic solvents and highly fluorescent in solid state. The maximal EL emissions of the devices based on the copolymers are in the range of red, and slightly red-shifted gradually with increasing BSeD's contents. The maximal external quantum efficiency of the devices reaches 1.0%.
