An anthracene-based deep blue organic electroluminescent material with high efficiency and low roll-off |
| abstract |
The invention discloses an anthracene-based deep blue organic electroluminescent material, which is characterized in that the organic electroluminescent material has the general structure shown in the following formula I; wherein, D is an electron donating group; A is an electron withdrawing group group; m and n are respectively the number of bridging groups, and the selected value is independently selected from 0 or 1. The invention obtains a class of anthracene-based deep blue organic electroluminescent materials with high efficiency and low roll-off by controlling the internal structure of the general formula, especially by optimizing and regulating electron-donating and electron-withdrawing units and bridging groups ; These anthracene-based deep blue organic electroluminescent materials can be especially applied to non-doped organic electroluminescent devices, thereby obtaining high-efficiency, low roll-off deep blue organic electroluminescent devices. |
