| 中文摘要 | new single-polymer electroluminescent systems containing two individual emission species - polyfluorenes as a blue host and 2,1,3-benzothiadiazole derivative units as an orange dopant on the main chain - have been designed and synthesized. the resulting single polymers are found to have highly efficient white electroluminescence with simultaneous blue(lambda(max) = 421 nm/445 nm) and orange emission (lambda(max) = 564 nm)from the corresponding emitting species. the influence of the photoluminescence (pl) efficiencies of both the blue and orange species on the electroluminescence (el) efficiencies of white polymer light-emitting diodes (pleds) based on the single-polymer systems has been investigated. the introduction of the highly efficient 4,7-bis(4-(n-phenyl-n-(4-methylphenyl)amino)phenyl)-2,1,3-benzothiadiazole unit to the main chain of polyfluorene provides significant improvement in el efficiency. for a single-layer device fabricated in air (indium tin oxide/poly(3,4-ethylenedioxythiophene): poly(styrene sulfonic acid/polymer/ca/al), pure-white electroluminescence with commission internationale de l'eclairage (cie) coordinates of (0.35,0.32), maximum brightness of 12 300 cd m(-2), luminance efficiency of 7.30 cd a(-1), and power efficiency of 3.34 lm w-1 can be obtained. |
