合成了以三-8-羟基喹啉铝（Alq 3）为交联剂的均聚物和一系列共聚物。所有这些聚合物都显示出比先前报道的对应物更高的电致发光（EL）效率。其中，含Alq 3和咔唑基团的共聚物显示出比均聚物更高的电致发光效率。我们还证明了使用均聚物通过光聚合生成图案的可行性。这些聚合物的交联性质、图案化的选择性、高热稳定性和EL效率可能使其成为制备大规模多层亚像素化有机发光二极管（OLED）的有希望的材料。
Homopolymers and a series of copolymers with tris-8-hydroxyquinoline aluminum (Alq 3 ) as the cross-links are synthesized. All these polymers show improved electroluminescence (EL) efficiency over their previously reported counterparts. Among them, the copolymers containing Alq 3 and carbazole groups show higher EL efficiency than that of the homopolymers. We also demonstrate the feasibility of generating patterns using the homopolymers via photopolymerization. The cross-linked nature, selectivity of patterning, high thermal stability, and EL efficiency might render these polymers a promising material in fabricating large-scaled multilayered sub-pixellation organic light-emitting diodes (OLEDs).
