摘要 |
This invention discloses a class of soluble poly(arylene-oxadiazole) polymers and copolymers comprising from 3 to 300 repeat units, which may be the same or different, represented by the formula: (I) wherein Arom can be a fluorene group, an aromatic hydrocarbon ring, an aromatic C2+ 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.
