A novel blue organic light emitting diode is fabricated based on a new organic material. Dipyrrole3, which can emit a pure blue light. The Dipyrrole3 is used as a dopant and is doped into an electron-transporting hose. NPB is used as the hole transport layer. The device consists structure or ITO/NPB/Begg2:Dipyrrole3 (100:5)/BePP2/LiF/Al. It shows a bright blue light emission layer at 451nm and 480nm, the full width at half maximum is 61nm. The maximum luminescence is 2600cd/m2 at a voltage of 20V. The peak power efficiency is 0.7651m/W at a voltage of 7V.
