摘要: An organic light diode (OLED) and an organic light emitting device comprising the OLED (e.g., a display device or a lighting device) are described. The OLED can comprise at least one emitting material layer including a first compound where an alkyl group is substituted to a specific position of an electron donor moiety and a second compound of a boron-based fluorescent material. Luminous properties in the OLED and the device can be improved as excitons generated at the first compound are transferred efficiently to the second compound.

摘要: An organic light emitting diode (OLED) and an organic light emitting device comprising the OLED are described. The OLED can comprise at least one emitting material (EML) disposed between two electrodes, where the EML can comprise a first compound comprising a fused ring having boron and oxygen and substituted with at least two fused hetero aromatic group, and a second compound comprising a fused ring having boron and nitrogen. The first compound and the second compound can be the same emitting material layer or be present in adjacently disposed emitting material layers. The luminous efficiency and luminous lifespan of the OLED can be improved by applying the first and second compounds, and adjusting their photoluminescence wavelength, absorbance wavelength and energy levels.
