The present invention provides a novel light-emitting material, which is a blue fluorescent material performs a high quantum yield of ˜86%, and can be doped into a host light-emitting layer of an organic light emitting diode (OLED) for being a guest light-emitting material, so as to increase the external quantum efficiency, the power efficiency and the current efficiency of the OLED. Most importantly, a variety of experiment results have proved that the OLED having the novel light-emitting material can emit a deep blue light with CIE coordinates of (0.156, 0.055). Moreover, the experiment results also proved that the novel light-emitting material can be applied in fabricating OLED through dry process and/or wet process; so that, the novel light-emitting material is helpful to the low-cost mass production of OLEDs.
