-
, (2018/03/26)
The invention relates to a fluorene-based organic compound and application thereof on an OLED device. A structure of the compound is that fluorine is connected with a hexatomic ring structure of a benzo hexatomic ring through a carbon-carbon bond, so that material chemical stability is improved and active positions of a branch chain radical are prevented from being exposed through the carbon-carbon bond connection; the whole molecule is a relatively great rigid structure, and has relatively high triplet-state energy level (T1); moreover, steric hindrance is great, rotation is not liable to occur and the three-dimensional space structure is more stable, so that the compound has a relatively high glass transition temperature and relatively high molecule thermal stability; besides, distribution positions of HOMO and LUMO of the compound are separated from each other, so that the fluorene-based organic compound has proper HOMO and LUMO energy level; and after the compound is applied to theOLED device, light-emitting efficiency of the device can be effectively improved, and the service life of the device can be effectively prolonged.
