Paragraph 0058; 0059; 0060, (2019/01/05)
The present invention provides a heterocyclic compound and its organic light-emitting device, which belongs to the technical field of organic photoelectric material. In particular in the specific position of the naphthalene ring is introduced on the amide group, thus can be appropriate adjusting hole mobility, reach the hole mobility and balance the purpose of carrier mobility. The exciton consistent with the regional totally in the luminescent layer. Heterocyclic compounds at one side of the amide group on the amine structure connected, increase its hole transmission ability. At the same time a relatively large molecule volume and molecular weight it ensures that this material has higher glass transition temperature. In the prior art can be effectively solve the organic photoelectric material luminous efficiency is low, the driving voltage is relatively high, and short service life of the technical problem of poor performance of the. Compared with the prior art, the invention is based on organic electroluminescent material and ink composition of the organic light-emitting device, can significantly improve the luminescence, is an excellent OLED material.

2-Azidoperimidine and its 1-methyl, 1-benzyl, and 1-phenyl derivatives were synthesized by the action of sodium azide on the corresponding 2-chloroperimidines.The IR spectra constitute evidence for the existence of all of these compounds in both the solid
