The invention discloses a white light hyperbranched conjugated polymer with a two-color core prepared based on the principle of red, green and blue three primary colors. Green and red phosphorescent Ir(Ш) complexes are used as the core of the hyperbranched structure, and polyfluorene derivatives The blue fluorescent material is the skeleton of the hyperbranched structure, and the hyperbranched conjugated polymer that can emit white light can be obtained by adjusting the content of green and red phosphorescent Ir(Ш) complexes. The electroluminescence spectrum of the conjugated polymer of the present invention has higher color saturation, close to pure white light emission, and has better electroluminescence performance, and can be used as a light-emitting layer material to prepare white-light organic electroluminescence with a single light-emitting layer device. |
