Paragraph 0044; 0045, (2017/07/19)
The present invention provides a heterocyclic derivative and the use of the heterocyclic derivatives of organic light-emitting device, which belongs to the technical field of organic photoelectric material. The invention heterocyclic derivatives through the molecular structural design, selection of the spiro compounds, through the spiro an effective molecular configuration twist, thereby reducing the film forming of the material after space orientation, to further improve its performance in the device, by changing the connection of the group, can further improve its physical characteristics, thereby improving the characteristics of the organic light-emitting of the light emitting device. The use of the present invention provides heterocyclic derivatives for preparing organic light-emitting device, the larger the increase of the light emitting device efficiency and luminous intensity, the performance is good organic light-emitting material.
