Paragraph 0181-0186, (2019/04/06)
The invention relates to a phenanthroimidazole symmetric derivative host material. The structure of the host material is represented by formula I, and can be used to form an organic electroluminescent device with the advantages of high luminescence efficiency, low driving voltage, long life, high brightness and high color purity. In the formula I, R1 and R2 are respectively independently selected from the hydrogen atom, substituted or unsubstituted C1-C30 alkyl groups, C1-C30 cycloalkyl groups, C1-C30 saturated alkyl groups, substituted or unsubstituted C1-C30 alkyloxy groups, substituted or unsubstituted C6-C30 aryl groups, substituted or unsubstituted C6-C30 aryloxy groups, substituted or unsubstituted C6-C30 arylamino groups, substituted or unsubstituted C2-C30 heterocyclic groups, substituted or unsubstituted C6-C30 fused polycyclic groups, hydroxy groups, cyan groups or substituted or unsubstituted amino groups.
