摘　　要：Conjugated ployfluorene with 2-（2-（2-methoxyethoxy）ethoxy）ethyl groups （EO-PF） is prepared by the palladium- catalyzed Suzuki coupling reaction. The polymer is purified carefully by a simple chemical procedure. The inductively coupled plasma （ICP） test shows palladium-catalyst in the polymer can be removed by this procedure. The thermal properties, electrochemical properties, UV-Vis absorption properties, photoluminescence properties and electroluminescent properties of the polymer without （EO-PF1） or with purification （EO-PF2） are studied. EO-PF2 shows better PL CIE coordinates in THF solutions as blue light-emitting materials and better photoluminescence stability in thin solid films. Polymer light emitting diodes and electrochemical cells based on EO-PF2 exhibit somewhat improved optoelectronic performance than control devices of EO-PF 1.Conjugated ployfluorene with 2-（2-（2-methoxyethoxy）ethoxy）ethyl groups （EO-PF） is prepared by the palladium- catalyzed Suzuki coupling reaction.
