-
Paragraph 0193-0197, (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.
Isoquinoline compound and its preparation method, the organic electroluminescent device
-
Paragraph 0160; 0161-0166, (2018/03/24)
The invention provides isoquinoline compounds and a preparation method thereof, and an organic light emitting diode. The isoquinoline compounds are as shown in a molecular formula (I) in the specification. Compared with the prior art, the isoquinoline compounds provided by the invention are prepared by introducing Q1, Q2, Ar1, Ar2, Ar3 and Ar4 groups into benzo[g]isoquinoline compounds, so electronic density and skills can be improved; meanwhile, R1 can improve performances of the isoquinoline compounds, so the organic light emitting diode containing the isoquinoline compounds as shown in the molecular formula (I) has the characteristics of high brightness, good heat resistance, long service life, high efficiency, etc.
