Disclosed are a terbenzocyclopentadiene compound of better solubility and film-forming property, and a high polymer, mixture, composition and organic electronic device comprising same. This terbenzocyclopentadiene compound contains a benzocyclopentadiene structure. The matching of energy level and the symmetry of the structure provide a possibility for increasing the chemical/environmental stability of terbenzocyclopentadiene compounds and photoelectric devices. This terbenzocyclopentadiene compound has a better solubility in an organic solvent, and also facilitates forming a high-quality film by a printing method due to a high molecular weight. After this terbenzocyclopentadiene compound is used in OLED, particularly as a luminescent layer material, a higher quantum efficiency, luminescence stability and device life time can be provided. |
