The invention discloses an electroluminescence material capped with 9-phenylfluorene, a preparation method and application thereof. The electroluminescent material has a five-membered ring structure as the core, and is respectively C-C or C-N coupled with aniline group derivatives, and then capped with 9-phenylfluorene. The structural formula is as follows: formula (I) or Formula (II) shown. This kind of material has mild reaction conditions, simple post-treatment, and easy industrial production; the electroluminescent material has high molecular weight, good solubility and film-forming property, and can be formed into a film by solution method; it has advantages in synthesis, purification and device preparation. The fields of organic/polymer light-emitting diodes and organic laser diodes have important application prospects. |
