Abstract: 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.
