Spirofluorene-based polymer and organic electroluminescent device using the same |
摘要 |
A spirofluorene-based polymer which contains a spirofluorene structure as a basic unit and which is end-capped with functional moieties substituted by fluorine, and an organic electroluminescent device using an organic layer using the spirofluorene-based polymer. The organic electroluminescent device has improved efficiency, reduced driving voltage, and excellent thermal, optical and electrical stability.
