| titleOfInvention | Organic electroluminescent compound, preparation method and application thereof |
| abstract | The invention relates to the technical field of luminescent compounds, in particular to an organic electroluminescent compound, and a preparation method and application thereof. In order to solve the problems of the conventional hole transport materials and to obtain a desired material, the present invention proposes a solution of introducing arylamine and anthracene derivatives to the 9-position of fluorene. Hole injection capability/transmission capability, high power efficiency and long service life are obtained by introducing arylamine; the anthracene derivative is introduced to obtain a proper glass transition temperature, so that the organic electroluminescent compound with high quality is obtained. Devices prepared from the compounds provided by the present invention have excellent current and power efficiencies and long lifetimes. The preparation method of the organic electroluminescent compound provided by the invention is simple and feasible, has high yield and is suitable for industrial production. |
