* Question
| What are the main electroluminescent polymer materials? |
* Answer
| (1) A main chain polymer having an isolated chromophore structure.(These materials can be further divided into several categories. 1 polyphenyls and their derivatives, such as polyparaphenylene (PPP) and its derivatives, polythiophene (PAT) and its derivatives, polypyrrole (PAP)Polypyridine (PPY) and its derivatives.
(2) a flexible backbone polymer with pendant chromophores, such as polyvinyl carbazole (PVK), in the side chain of non-electroluminescent materials such as polyethylene, which has good hole-conducting ability and is therefore often used.Make a hole transport material. |
