BISCARBAZOLE DERIVATIVE FOR ORGANIC ELECTROLUMINESCENT DEVICE AND ORGANIC ELECTROLUMINESCENT DEVICE INCLUDING THE SAME

摘要

The present invention relates to a compound for biscarbazole based organic electroluminescent device and an organic electroluminescent device including the same. The biscarbazole based compound of the present invention is represented as following structural formula 1. The organic electroluminescent device by using the structural formula 1 improves the thermostability and the luminous efficiency; and improves efficiency of organic electroluminescent device by using the biscarbazole based derivatives as a hole transport layer material which contacts to luminous layer thereby binding the triplet exciton of the phosphorescence luminous substance.
