제목 Development of New Blue-Emitting Material for OLED
초록 In this study, we designed and developed new blue-emitting material with high color purity and efficiency for OLEDs. The new blue-emitting material was synthesized via the Suzuki cross coupling reaction. The structure of new material was confirmed by using FT-IR, 1H-, 13C-NMR, and mass spectroscopy. The optical, electrochemical and thermal properties have been investigated, and the molecular structure-property relationships were evaluated.
The non-doped devices using EFPA displayed 2.55% maximum external quantum efficiency (EQE) with CIE color coordinates (0.166, 0.197). The doped device using 5% EFPA as a dopant showed maximum EQE of 2.90% and CIE coordinates of (0.142 0.107).
