Title:
イリジウム含有の有機エレクトロルミネセンス材料及びその調製方法並びに有機エレクトロルミネセンス素子
Document Type and Number:
Japanese Patent JP5593456
Kind Code:
B2
Abstract:
The invention provides an iridium-containing organic electroluminescent material, the formula of which is H:
wherein R is C 1 -C 8 alkyl. The molecule of the iridium-containing organic electroluminescent material contains benzimidazole group with electron transmission function and the benzimidazole has alkyl and fluorobenzyl group, which can improve the electron injection and transmission function of the electroluminescent material, and enable the electroluminescent material to have higher internal quanta efficiency and electroluminescent efficiency. The invention also provides a preparation method of the iridium-containing organic electroluminescent material, and an organic electroluminescent device using the material.
