The invention provides an organic light-emitting material based on a donor-receptor structure of a benzo[c][1,2,5]thiadiazole-4-aldehyde group receptor and a 2-(benzo[c][1,2,5]thiadiazole-4-methylene)malononitrile receptor and application thereof. The organic light-emitting material is a receptor-donor separation system, wherein the receptor is benzo[c][1,2,5]thiadiazole-4-aldehyde or 2-(benzo[c][1,2,5]thiadiazole-4-methylene) malononitrile, and a donor is carbazole and a derivative or benzoxazine and the like. The lowest unoccupied molecular orbital (LUMO) in the material is located in the receptor, and the highest occupied molecular orbital (HOMO) in the material is located in the donor, so that the molecular orbital energy level of the luminescent material can be effectively regulated and controlled through electrical regulation of the receptor structure and the donor. By regulating and controlling the structure of the light-emitting material or the electron donating capability of the donor, the light-emitting color of material molecules can be conveniently regulated. The organic light-emitting material has the characteristic that the light-emitting color is easy to adjust, andcan be used as a light-emitting material for preparing an OLED device.

New ethylene-separated benzothiadiazoles were synthesized for the first time by using a facile procedure, and they showed lower bandgaps than the reported benzothiadiazole-containing compounds. This new benzothiadiazole- containing unit could be introduced into the backbone of the π-conjugated small molecules or polymers to develop new materials with a low bandgap that may have potential applications in optoelectronic fields.
