我们已经合成了芴基共聚物PFA-OXD,该共聚物具有双极性电荷传输功能,方法是将富电子的三苯胺部分和缺电子的恶二唑侧基结合到聚合物主链中以及每个芴重复的C9位置上单位。主链中的螺旋状三苯胺单元和刚性的Cardo型OXD侧链使该聚合物具有很高的玻璃化转变温度(306°C)和良好的热稳定性,而不会牺牲其良好的溶液可加工性。无论是在稀溶液中还是作为薄膜,PFA-OXD在激发主链或恶二唑侧链时均显示出亮蓝色发射。该现象表明从光激发侧基到聚合物主链发生了有效的能量转移。将该共聚物作为发光层的有机发光元件在9V下显示出电压独立且稳定的蓝色发光,其色坐标为(0.14,0.15)。最大亮度为7128 cd m-2,最大亮度效率为2.07 cd A -1。另外,用2.6 wt%的发红磷光染料Os(fppz)掺杂PFA-OXD作为主体材料,导致了CIE坐标为(0.65,0.34)的高亮度,高效红色电致发光器件,最大亮度为28

critical issue when attempting to improve the charge transport and stabilize the operation of solution-processedorganiclight-emittingdiodes (OLEDs). Herein, we describe a simple methodology for overcoming interfacial mixing, based on the use of a photo-crosslinkable holeinjection/transporting material (HITM). We synthesized a conjugated polymer, PTCAzide, bearing ready crosslinking ability and

stability, without sacrificing its good solution processability. Both in dilute solution and as a thin film, PFA-OXD exhibits a bright blue emission upon excitation of either the main chain or oxadiazole side chains; this phenomenon indicates that efficient energy transfer occurs from the photoexcited pendent groups to the polymer backbone. An organic light-emitting device incorporating this copolymer
