N-heterocyclic planar optical coupling output material and preparation method therefor |
| abstract |
The present invention provides an improved N-heterocyclic planar optical coupling output material. The general structural formula of the N-heterocyclic planar optical coupling output material is R 1 -R 2 -R 1 . The structural formula of the synthesized output material can be selected from any one of the following structures: (I). The optical coupling output material of the present invention has a very high n value, so that a top-emitting electroluminescent device using same has a high efficiency, saves time and reduces capital cost. The present invention further provides a method for preparing an N-heterocyclic planar optical coupling output material. |
