The invention discloses a carbazolo-aromatic ring thermal activation delayed fluorescence material and an organic electroluminescent device. The structural formula of the carbazolo-aromatic ring thermal activation delayed fluorescent material is shown in the specification. The carbazolo-aromatic ring thermal activation delayed fluorescent material provided by the invention takes a carbazolo-aromatic ring as a core; due to the large volume and rigidity, molecules have a steric hindrance effect, intramolecular distortion is realized, and electron clouds of the highest occupied orbit and the lowest empty orbit of the molecules can be relatively separated to obtain a quite small single triplet state energy level difference, so that light-emitting molecules with a thermal activation delayed fluorescence property are designed and prepared; the thermal performance, the light-emitting efficiency and the light color of the material can be adjusted, and the material can be used as a guest material, can also be used as a host material by utilizing the thermal activation delayed fluorescence property, and can be constructed through molecular design.
