-
Paragraph 0048-0051, (2020/08/09)
The invention relates to a cross-linked hole transport material of a quantum dot electroluminescent diode as well as a preparation method and application thereof. The hole transport material comprisesa compound as shown in a general formula I. In the formula I, R1 is selected from one of phenyl or substituted phenyl, biphenyl or substituted biphenyl, naphthyl or substituted naphthyl, phenanthreneor substituted phenanthrene, pyrenyl or substituted pyrenyl; R2 is selected from-R3-CH2 = CH2, R3 is selected from one of phenyl or substituted phenyl, biphenyl or substituted biphenyl, and-CH = CH2is connected to a benzene ring of an R3 group. The hole transport material is a cross-linked small organic molecule taking 1, 1-bis (4-aminophenyl) cyclohexane as a core and benzene, biphenyl, naphthalene, phenanthrene, pyrene and styrene as side groups. The synthesis is simple and suitable for large-scale production; and the material has high hole mobility and proper HOMO energy level, has good anti-solvent property after crosslinking, can be used as a hole transport material to be applied to a printing type quantum dot electroluminescent diode, and has great application prospect.
