The invention belongs to the technical field of organic light-emitting materials, and in particular relates to a light-emitting macrocyclic TADF compound and a preparation method and application thereof. The compound uses an aniline derivative as the donor group and has many replaceable acceptor structures. The luminescent color and luminescent properties of the compound can be changed by changing the electron acceptor (Acceptor, A) and electron donor (Donor, D). , which provides a new idea for constructing a variety of luminescent macrocyclic TADF molecules. In addition, experiments have shown that the macrocyclic compound has high luminescence intensity, and the photoluminescence quantum yield has also been significantly improved, which can be applied to the field of organic optoelectronic materials. |
