The invention discloses an organic photoelectric material which is in a non-conjugated annular shape. The left side and the right side of the organic photoelectric material are provided with donor units, the middle of the organic photoelectric material is provided with a receptor unit, and a certain torsion angle is formed between each donor unit and the receptor unit; the organic photoelectric material has a big energy gap and easily has the smaller delta(EST), and therefore thermal activation delayed fluorescence (TADF) can be easily achieved; the organic photoelectric material can be fully used as a blue-light thermal activation delayed fluorescence material, and the application that the organic photoelectric material can be applied to an organic luminescent device, especially a blue-light device is expanded. The invention further discloses a preparation method of the organic photoelectric material. Synthesizing is easier, purifying is very easy, and the yield is very ideal.

A series of bipolar materials for thermally activated delayed fluorescence based on 3,6-di-tert-butyl-9-((phenylsulfonyl)phenyl)-9H-carbazoles, is synthesized by Ulmann coupling reactions. In these materials, the 3,6-di-tert-butylcarbazole group is linked at the 3-, 4- position or 3′-, 4′- position of diphenyl sulfone. The effects of the conjugation connectivity on the electronic, photophysical and electrochemical properties of these materials, are studied by extensive UV-vis, fluorescence spectroscopic measurements, cyclic voltammetry and theoretical calculations as well as X-ray crystallographic analysis. The energy gap between singlet and triplet in these materials is tuned from 0.39 eV to 0.22 eV by manipulation of conjugation of the electron donor units.
