Preparation method of 2-(4-biphenyl)amino-9,9-dimethylfluorene

The invention belongs to the field of organic synthesis and provides a preparation method of a novel liquid crystal material 2-(4-biphenyl)amino-9,9-dimethylfluorene. The preparation method is characterized in that fluorene is subjected to methylation with methyl iodide to obtain 9,9-dimethylfluorene, 9,9-dimethylfluorene is subjected to nitration with nitric acid to obtain 2-nitro-9,9-dimethylfluorene, 2-nitro-9,9-dimethylfluorene is subjected to hydrazine hydrate reduction to obtain 2-amino-9,9-dimethylfluorene, and 2-amino-9,9-dimethylfluorene is subjected to reaction with bromobiphenyl toobtain 2-(4-biphenyl)-amino-9,9-dimethylfluorene; the structure of the 2-(4-biphenyl)-amino-9,9-dimethylfluorene is characterized via 1H-NMR, 13C-NMR, IR and MS. The 2-(4-biphenyl)-amino-9,9-dimethylfluorene has good thermostability and high glass transition temperature and is applicable to hole transport materials in organic light-emitting devices.
