摘要： A white-light organic electroluminescent material based on 8-hydroxyquinoline and the method for preparing the same, as well as an organic light emitting diode including this material. The material may be the compound represented by the Formula (IX) having a DCDC group, a 5-position substituted 8-hydroxyquinolinyl group and a carbazolyl group as red light-, green light- and blue-light emitting groups, respectively. It exhibits a spectrum having a band width of 182.4 nm that substantially covers the visible-light region, and has a color coordinate of (0.3177, 0.3946), which just locates within the white-light area. Such a material is capable of realizing a white-light emission, and may be used in a white-light OLED as a single light-emitting layer, which can decrease the number of layers of the white-light OLED and thereby improve the luminous efficiency, stabilize the light color, lower the turn-on voltage and simplify the fabrication process.
