The invention relates to the technical field of organic electroluminescent materials and particularly relates to a compound, a light-emitting material, a device and a display device. The compound hasa structure expressed by a formula which is as shown in the description. The compound can be used as a thermally activated delayed fluorescent (TADF) material. When the compound is used as a light-emitting material or a main body material of a light-emitting layer of an organic light-emitting device, the compound can achieve high light-emitting efficiency.

The invention relates to an aromatic heterocyclic compound having a thermal active delay fluorescence (TADF) property, having a structure represented by a formula (I), wherein X1 and X2 are selected from S or O respectively; D represents a chemical group as an electron donor, and A represents a chemical group as an electron acceptor; m represents the number of electron donors D linked to the formula (I), and the electron donors D are the same or different; n represents the number of the electron acceptors linked to the formula (I), and the electron acceptors A are the same or different; m andn are 1 or 2 independently. The luminescence mechanism of the aromatic heterocyclic compound disclosed by the invention is thermal active delay fluorescence, and therefore high luminescence efficiencyis achieved. When the compound is used as a luminescent material, a luminescent host material or an object material in an organic light-emitting display device, the luminescent efficiency of the organic light-emitting display device can be improved, and the advantages of lower cost and longer service life are achieved.
