| titleOfInvention | Organic small molecule light-emitting materials and organic electroluminescent devices |
| abstract | The present invention provides an organic small molecule light-emitting material and an organic electroluminescent device. The organic small molecule light-emitting material of the present invention is obtained by coupling a novel acridine donor unit 10H-spiro[acridine-9,2'-adamantane] with an acceptor unit, the structure is single, the molecular weight is determined, and the purification is convenient , multiple synthesis reproducibility is good, with lower sublimation temperature and higher decomposition temperature, the film shape is stable, and due to the non-aromatic rigid structure adamantane as the donor part of the structure, the organic small molecule light-emitting material in the film state It has a very high photoluminescence quantum yield, and when applied to organic electroluminescence devices, it can effectively solve the problem of low device efficiency caused by severe non-radiative decay of excited state molecules due to configuration relaxation. |
