The application belongs to the technical field of OLED and specifically comprises an organic compound for a blue light device and a blue light organic electroluminescent device. The structural general formula of the organic compound is shown in the following. The application directly connects a benzofuranphenanthrol group to the 12th position of a benzanthracene nucleus, which can utilize the oxygen atom on the furan to increase the polarity and intermolecular interaction of the molecule, improve the molecular orientation when the material is stacked, thereby strengthen the permanent spontaneous orientation polarization effect, and obtain a better voltage improvement effect; on the other hand, the direct connection of the phenanthrene ring on the benzofuranphenanthrol group to the 12th position of the benzanthracene can improve the electron mobility of the material, thereby improving the electron density in the light-emitting layer, and with the increase of the electron density, the carrier recombination probability can be significantly improved, thereby reducing the accumulation of holes in the light-emitting layer, reducing the exciton quenching condition, and improving the device efficiency.I

The application belongs to the technical field of OLED and specifically comprises an organic compound for a double light-emitting layer blue light device and a double light-emitting layer blue light organic electroluminescent device comprising the same. The structural general formula of the organic compound is shown in the following. By introducing a triphenyleno[1,12-bcd]furan group on a benzanthracene nucleus, the benzanthracene nucleus has a rigid planar structure, weak electron-withdrawing ability, and excellent thermal stability and chemical stability. In addition, the triphenylene skeleton also has an energy level structure suitable for a multi-channel high-energy level reverse intersystem crossing process. After connecting the triphenyleno[1,12-bcd]furan structure and the benzanthracene nucleus directly, the HOMO and LUMO energy levels of the material can be regulated, the carrier injection barrier is reduced, and the prepared double light-emitting layer device has a significant improvement in voltage, efficiency and lifetime.I.
