设计并合成了一种新型的含双极性芴低聚物侧基的聚芳醚蓝色发光材料，其中嘧啶和芳胺分别作为电子受体和电子给体。通过改变π桥长，从单芴到双芴，从氢到咔唑和二苯胺，聚合物的发光颜色从深蓝色到蓝绿色，并且可以调节其HOMO和LUMO能级，以促进电荷注入，从而改善器件性能。制备了ITO/聚（3，4-乙撑二氧噻吩）：聚苯乙烯磺酸（PEDOT：PSS）（50 nm）/聚合物（80 nm）/Ca（10 nm）/Al（200 nm）结构的聚合物发光二极管（PLED）。在这些聚合物中，具有联芴桥和咔唑封端剂的P2Cz 5 F-Py显示出在效率和发射波长之间的优异折衷，具有高达1.26cd/A的峰值发光效率和国际照明委员会（CIE）坐标（0.17，0.17）。
Novel blue light-emitting poly(aryl ether)s comprising of bipolar oligofluorene pendants as chromophores have been designed and synthesized, in which pyrimidine and arylamine moieties are utilized as the electron acceptor and electron donor, respectively. Through varying π bridge length from monofluorene to bifluorene and end-cappers from hydrogen to carbazole and diphenylamine, the emission color of the resulting polymers covers from deep blue to greenish blue, and their HOMO and LUMO levels can be modulated to facilitate charge injection to improve the device performance. Polymer lightemitting diodes (PLEDs) are fabricated with the device structure of ITO/poly(3,4-ethylenedioxythiophene):poly(styrene sulfonic acid) (PEDOT:PSS) (50 nm)/polymer (80 nm)/Ca (10 nm)/Al (200 nm). Among these polymers, P2Cz5F-Py with bifluorene bridge and carbazole end-capper shows excellent trade-off between the efficiency and emission wavelength, having a peak luminous efficiency as high as 1.26 cd/A and Commission Internationale de L’Eclairage (CIE) coordinates of (0.17, 0.17).
