The invention relates to design and synthesis of organic electroluminescence materials which take 1,2,4-thiadiazole electronics transmission groups as a central unit as well as an application of the 1,2,4-thiadiazole electronics transmission groups on an organic electroluminescent device (OLED). The electroluminescent materials take 1,2,4-thiadiazole as a core, groups with different electronic or cavity transmission groups are bonded at positions 3 and 5 sites of 1,2,4-thiadiazole, carrier balance can be effectively solved, exciton recombination with high efficiency is radically realized, thus further combination of high efficiency light-emitting and energy level adjustment of the material can be realized. In addition, the energy level of the compound can be adjusted through an unsymmetrical structure, compared with the electronics transmission groups (such as oxadiazoles, 1,3,5-triazole) in the common main materials, the OLED devices has substantial effects in brightness, efficiency, glass transition temperature and the like, so that the material provided in the invention can be widely applied in the field of organic electroluminescence.
