摘要： The present invention provides a B/N organic electroluminescent material and its preparation method and use, as well as the corresponding organic light-emitting device. The B/N organic electroluminescent materials DBTN-1 and DBTN-2 in the present invention show narrowband green emission both in dilute solution and doped film, with extremely high photoluminescence quantum yields and efficient thermally activated delayed fluorescence feature. In particular, the organic light-emitting devices based on the above fluorescent dye exhibit ultra-pure green electroluminescence with high efficiencies and high color purity, which can be applied to usages such as ultra-high definition display technology.
