the corresponding homopolymers are prepared. These side‐chain polymers show high glass‐transition temperatures that even exceed the corresponding value for the common electron‐transporting material 1,3,5‐tris(1‐phenyl‐1H‐benzo[d]imidazol‐2‐yl)benzene (TPBI). Similar electronic behavior between the polymers and TPBI is shown. The polymers are used as matrices for phosphorescent dopants. The fabricated
制备了一系列具有苯基苯并[ d ]咪唑单元的新型苯乙烯官能化单体和相应的均聚物。这些侧链聚合物的玻璃化转变温度很高,甚至超过了普通电子传输材料1,3,5-三(1-苯基-1 H-苯并[ d ]咪唑-2-基)苯的相应值。 (TPBI)。显示了聚合物和TPBI之间的相似电子行为。该聚合物用作磷光掺杂剂的基质。所制造的器件在100 cd m -2的电流效率高达38.5 cd A -1,最大亮度为7400 cd m -2 在具有ITO / PEDOT:PSS阳极(ITO =氧化铟锡,PEDOT:PSS =聚(3,4-乙二氧基噻吩))的单层器件中,在10 V时的最小开启电压低至2.70 V (苯乙烯磺酸盐))和CsF / Ca / Ag阴极。
