Paragraph 0085-0087; 0090-0091, (2018/10/19)
The invention provides a polyfluorene derivative and an organic light-emitting device thereof, and belongs to the technical field of organic photoelectric materials. The derivative has a structure shown as a formula (I). The polyfluorene derivative disclosed by the invention has a larger conjugate plane structure, so that high electron fluidity can be provided; electron-deficient group dibenzofuran, dibenzothiophene, acridine, phenoxazine and phenothiazine structures are introduced to better facilitate the acception of electrons and enable the polyfluorene derivative to have good transmissionperformance; by introducing a bridged structure, on the one hand, the molecular weight of the compound can be enlarged, and the obtained material is enabled to have high glass transition temperature and prevent the crystallization effect; on the other hand, the derivatives are enabled to have certain distortion in three-dimensional stereoscopic structure, and the film-forming property of the derivative is improved. The organic light-emitting device, which is prepared by using the compound as a main body material in a luminescent layer, shows the advantages of low driving voltage and high luminous efficiency; the polyfluorene derivative is an organic luminescent material with excellent performance.
