This invention discloses a class of soluble poly(arylene-oxadiazole) polymers and copolymers comprising at least 20 repeat units, which may be the same or different, represented by the formula:
1
wherein Arom can be a fluorene group, an aromatic hydrocarbon ring, an aromatic C
2+
heterocyclic ring, or two aromatic rings linked by a single bond, ethenyl bond, or ethynyl bond. A process for preparing the polymers and copolymers by reacting dicarboxylic acids and hydrazine salt is provided. The polymers are useful in electroluminescent devices, photovoltaic cells, and diodes.
本发明公开了一类由至少 20 个重复单元组成的可溶性聚(芳基烯-噁二唑)聚合物和共聚物,这些重复单元可以相同或不同,由式表示:
1
其中 Arom 可以是芴基、芳香烃环、芳香 C
2+;
杂环,或由单键、乙烯键或乙炔键连接的两个芳香环。提供了一种通过二羧酸和肼盐反应制备聚合物和共聚物的工艺。这些聚合物可用于电致发光装置、光伏电池和二极管。
