The invention discloses a hyperbranched white light conjugated polymer and its preparation method and application. The polymer uses a red phosphorescent Ir(Ш) complex as the core, a polyfluorene derivative blue fluorescent material as the skeleton, and the skeleton contains or It does not contain carbazole derivatives, and by adjusting the content of the red phosphorescent Ir(Ш) complex, the hyperbranched white light conjugated polymer realizes white light emission by using the complementarity of blue and red. The electroluminescence spectrum of the conjugated polymer of the invention covers the entire visible light emission region, close to pure white light emission, and can be used as a light-emitting layer material to prepare an organic electroluminescence device. |
