Efficient deep blue-violet fluorophores are highly sought after as emitters for OLEDs and as labels for fluorescent imaging. Despite significant progress in the development of deep blue luminescent materials, highly efficient emitters in the deep-blue/violet region of the visible spectrum with good photostability remain rare. Here we describe the preparation of two violet-blue emitters based on hexamethylazatriangulene (HMAT) donors and weakly accepting sulfone and sulfoxide acceptors, with CIE coordinates in solution as low as (0.16, 0.02) and quantum yields of unity. By restricting freedom of motion in the HMAT donor, stability of the sp2 C-N bonds is increased significantly, increasing photostability over controls with nonplanar donors while also narrowing the emission bandwidth to 39.5 nm FWHM. These materials were then evaluated in proof-of-concept experiments for both two-photon excited fluorescence and as emitters in OLEDs to demonstrate their potential applications in optoelectronics.

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 field of organic photovoltaic devices and organic electroluminescence devices.
