Abstract: Poly(p-phenylenevinylene) derivatives, with large-conjugated systems, are the most well-studied conjugated polymers due to their excellent luminescent and mechanical properties. As electroluminescent materials, PPV derivatives have good flexibility, low threshold voltage, tunable band gaps, etc. The structures of PPVs are multiple, because they can be designed and synthesized by different methods. This article summarizes the recent progress of electroluminescent PPVs and discusses the prospect of application.
