제목 Enhancement of external quantum efficiency through sterichindrance of phenazine derivative for white polymer light-emitting diode materials
초록 Polymer light-emitting diodes (PLED) present advantages in large-area fabrication methods, such as ink-jet and screen printing with solution processes. As a result, the material has drawn great attention as a next-generation material to replace vacuum deposition with small molecules. Thanks to its convenience and flexibility, polymer film has been popular in the flexible display sector. In this study, 0.03–0.1 mol% of phenazine derivative was adopted as dopant with an orange emitter and PF as a host. The Forster energy transfer was investigated, as well as the charge trapping and quantum efficiency between host and dopant, and the optimum mol concentration for effective white-emitting polymer was realized.
