The invention discloses a phosphorescent iridium complex serving as an OLED (organic light emitting diode) doping material. According to the iridium complex, metal iridium is taken as a structural inner core and applied to an OLED device and can emit phosphorescence under the action of an electric filed as a doping material of a luminous layer material. The phosphorescent iridium complex serving as the luminous layer doping material has good photoelectric performance and can be applied to OLED illumination or OLED display fields.
