Paragraph 0064; 0065; 0066, (2014/09/16)
The invention provides an iridium-containing organic electroluminescent material, the formula of which is H: wherein R is C1-C8 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.
