Abstract
This application discloses a white-light hyperbranched conjugated polymer, a method for preparing the same and its use. The polymer uses a red phosphorescent Ir(III) complex as a core and polyfluorene derivative blue fluorescent materials as a framework which either contains or does not contain carbazole derivatives, and the white light hyperbranched polymers realize white-light emission by adjusting the content of the red phosphorescent Ir(III) complex connected using the complementation of blue and red color. The electroluminescent spectrum of the conjugated polymer in the present application covers the whole visible light emission area and is close to the pure white light emission, by which the conjugated polymer could be used as a material used in light-emitting layer to prepare the organic electroluminescent devices.
