| 中文摘要 | by incorporating a new building block, 7,7,15,15-tetraoctyldinaphtho-s-indacene (nsi), into the backbone of poly(9,9-dioctylfluorene) (pfo), a novel series of blue light-emitting copolymers (pfo-nsi) have been developed. the insertion of the nsi unit into the pfo backbone leads to the increase of local effective conjugation length, to form low-energy fluorene-nsi-fluorene (fnf) segments that serve as exciton trapping sites, to which the energy transfers from the high-energy pfo segments. this causes these copolymers to show red-shifted emissions compared with pfo, with a high efficiency and good color stability and purity. the best device performance with a luminance efficiency of 3.43 cd . a(-1), a maximum brightness of 6 539 cd . m(-2) and cie coordinates of (0.152, 0.164) was achieved. |
