Planar triphenylamine derivative having crosslinkable group and synthesis method of same

The invention relates to a planar triphenylamine derivative having a crosslinkable group and a synthesis method of same, wherein the compound is synthesized through reactions such as Ullmann couplingreaction, Grignard reaction, ring-closing reaction, halogenation reaction and Suzuki reaction. The structure of the planar triphenylamine derivative is represented as the following structure, whereinF, G, H and I in the planar triphenylamine derivative have more than one of styryl or trifluorovinyl crosslinking groups, so that after crosslinking, an anti-solvent network thin film can be formed, and interlayer miscibility of a device is effectively prevented. The oxidization potentials of the F, G, H, I and J, tested by the cyclic voltammetry method, are 0.3 eV, 0.29 eV, 0.27 eV, 0.32 eV and 0.33 eV, respectively, which are lower than the oxidization potential (0.36 eV) of planar triphenylamine, which is beneficial to carrier transport. The planar triphenylamine derivative has important application prospect in the
