Title:
POLY-SPIROFLUORENE AND ORGANIC ELECTROLUMINESCENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/086044
Kind Code:
A1
Abstract:
The present invention provides a poly-spirofluorene represented by formula (I). In the present invention, a carbazole group is introduced to a side chain of spirofluorene to synthesize a polymer containing carbazole spirofluorene. The polymer containing carbazole spirofluorene prepared in the present invention does not have an intramolecular charge transfer effect from a primary chain to a side chain; and the polymer has a good hole transport capability due to the modification cation of the carbazole, and a good component efficiency can be achieved while the color purity of pure blue light is ensured. By introducing an aromatic group to the poly-spirofluorene in the present invention, transmission of three-primary colors that are blue, green and red can be obtained, thereby achieving the good component efficiency.
