| 中文摘要 | the dopant/host concept, which is an efficient approach to enhance the electroluminescence (el) efficiency and stability for organic light-emitting diodes (oleds) devices, has been applied to design efficient and stable blue light-emitting polymers. by covalently attaching 0.2 mol % highly fluorescent 4-dimethylamino-1,8-naphthalimide (dman) unit (photoluminescence quantum efficiency: phi(pl)=0.84) to the pendant chain of polyfluorene, an efficient and colorfast blue light-emitting polymer with a dopant/host system and a molecular dispersion feature was developed. the single-layer device (indium tin oxide/pedot/polymer/ca/al) exhibited the maximum luminance efficiency of 6.85 cd/a and maximum power efficiency of 5.38 lm/w with the cie coordinates of (0.15, 0.19). moreover, no undesired long-wavelength green emission was observed in the el spectra when the device was thermal annealed in air at 180 degrees c for 1 h before cathode deposition. these significant improvements in both efficiency and color stability are due to the charge trapping and energy transfer from polyfluorene host to highly fluorescent dman dopant in the molecular level. |
