| titleOfInvention | Organic electroluminescent material and preparation method thereof |
| abstract | The invention relates to an organic electroluminescent material and a preparation method thereof, solving the technical problem that the luminescent efficiency of existing luminescent materials still can not meet the requirements of an OLED (organic light emitting diode). The novel organic electroluminescent material is synthesized by using 3-methyl-7H-benzacridine as a basis and introducing one of phenyl, p-methylphenyl and p-methoxyphenyl as well as a C10-C16 polycyclic aromatic hydrocarbon substituent group. Compared with 3-methyl-7H-benzacridine, the synthesized green organic electroluminescent material has a larger plane structure and conjugated system and can change the electron transition energy level, thus changing the luminescent spectrum, improving the luminescent efficiency and being capable of meeting the requirements of the OLED. The preparation method of the organic electroluminescent material, which is provided by the invention, is relatively simple in synthesis and purification, easy in purification of materials and low in cost, and can meet the requirements of industrialization development. |
