Synthesis and Electroluminescence Properties ofNovel Deep Blue Emitting 6,12-Dihydro-diindeno[1,2-b;1',2'-e]pyrazine Derivatives |
| 초록 |
In recent, the range of applications of functional organic materials has rapidly expanded, with especially innovative uses discovered in the field of optoelectronics. Researchers have begun to report how the properties of functional organic materials can be modified by varying their core and side groups. A key research area is thus the development of new core and side groups and the study of how they combine in functional organic materials. In this study, we designed and synthesized a new core system, which we tested in organic light-emitting diodes (OLEDs). We report the synthesis of blue emitting materials with a new core structure containing indenopyrazine. Non-doped device using one of these materials as a blue emitter was found to exhibit high external quantumn efficiency of 4.6% and excellent color purity of (0.154, 0.078) as well as narrow emission band of 47nm FWHM. |
