    • 本篇中我們以spirobifluorene與一系列具有不同取代基的coumarin衍生物共聚合成高分子，利用旋轉塗佈法製成元件，進行光、電性質的探討。由於spirobifluorene為高剛性分子，因此這些高分子都具有相當高的Tg。以[ITO/PEDOT/polymer/ TPBI/LiF/Al]結構製成元件，其中效能最佳的元件放光波長位於442 nm，為相當純的藍光。起始電壓為6.7 V，最大亮度及最大外部量子產率分別為1244 cd/m2及1.32 %，最大發光效率及最大功率效率則分別為1.14 cd/A及0.43 lm/W。
    此外，有鑒於磷光元件具有發揮趨近100%的內部量子效率的潛力。我們也合成了一系列具有不同取代基的Iridium錯合物，作為磷光摻雜物，同樣與spirobifluorene共聚合成高分子並製成元件。所製成的最佳元件起始電壓為4.7 V，最大亮度及最大外部量子產率分別為3627 cd/m2及1.44 %，最大發光效率及最大功率效率也有4.03 cd/A及1.75 lm/W。

    We have synthesized a series of fluorene based copolymer with coumarin derivatives as dopant. The photophysical, electrochemical and electroluminescene properties of these copolymers has been systematically investigated. The glass transition temperatures of these copolymers are very high, since the rigidity of polyfluorene backbone. Pure blue electroluminescene was achieved from these copolymers as an emitting layer in light emitting device. A maximum brightness of 1244 cd/m2 and a maximum external quantum efficiency of 1.32 % was obtained in the configuration ITO/PEDOT/polymer/ TPBI/LiF/Al.
    Since Ir(III) complex is reported to have probable 100% internal quantum efficiency, we synthesized another series of fluorene based copolymer with different substituted groups on the Ir complex as dopant. The device produced a maximum brightness of 3627 cd/m2 and a maximum external quantum efficiency of 1.44 %.
