| titleOfInvention | Organic Small Molecular Electron Transport Materials Based on Naphthalimide Units and Their Applications |
| abstract | The invention provides an organic small molecule electron transport material based on a naphthalimide unit and an application thereof, belonging to the field of organic optoelectronic materials. The problems of less selection of electron transport materials and poor device stability in the quantum dot light-emitting diode device in the prior art are solved. The chemical structure of the organic small molecule electron transport material of the present invention contains a naphthalene diimide unit, which has the following advantages: 1) the lowest unoccupied molecular orbital energy level is low, which is beneficial to the injection and transport of electrons in the QLED device, and the highest occupied molecular orbital The low energy level can block the injection of holes in the QLED device. The above two aspects are beneficial to improve the electroluminescence efficiency of the QLED device; 2) The absorption spectrum is mainly not located in the visible light region, and the light emitted by the light-emitting layer in the QLED device is not. There is no absorption; 3) it has a rigid configuration, which can inhibit the crystallization of the material, which is beneficial to the processing in the QLED, and is beneficial to improve the stability of the QLED device. |
