The invention discloses an organic photoelectric material, which is in the form of a non-conjugated ring, with donor units on the left and right sides and acceptor units in the middle, with a certain torsion angle between them, a large energy gap, and easy The small △EST makes it easy to realize thermally excited delayed fluorescence (TADF), which can be fully used as a blue-light thermally excited delayed fluorescence material, expanding the applications that can be used in organic light-emitting devices, especially blue-light devices. The invention also discloses a preparation method of the above-mentioned organic photoelectric material, the synthesis is relatively simple, the purification is easy, and the yield is also ideal. |
