Abstract
The invention provides a silicon-containing bianthracene derivative, a production process and use thereof, and an organic electroluminescent device. The invention belongs to the technical field of organic electroluminescence, and can give a blue light-emitting material being able to form a dense film. The silicon-containing bianthracene derivative has a molecular structure of the following general formula, wherein R group represents an aryl group having a carbon atom number of 6-14, an aromatic heterocyclic group having a carbon atom number of 8-18, a fused-ring aromatic group having a carbon atom number of 9-15, a fluorenyl group, or a triarylamino group. The silicon-containing bianthracene derivative mentioned in the invention can be used in an organic electroluminescent device.
