Abstract :In this study we have presented the use of a organometallic compounds derivates insert ignore into journalissuearticles values(Keggin type polyoxometalates); for the production of powerful electron injection layer between the emissive polymer layer insert ignore into journalissuearticles values(PFO); and cathode layer insert ignore into journalissuearticles values(Al); . Electron transport studies in organometallic compounds layers showed efficient electron transport in very thin structures. High efficiency solution-processed organic light emitting diodes insert ignore into journalissuearticles values(OLEDs); are achieved by organometallic compounds  such as Keggin type polyoxometalates used as electron injection or transport layers with superb electron mobilities and hole blocking capacities. These results indicate the potential for organometallic compounds derivates as a variable, emerging new class of efficient electron injection/transport molecular materials for high performance air-stable HyLEDs. The Keggin type  polyoxometalates show unique features such as superior ionization energy and  low electron affinity which conversion them as efficient electron injection/hole blocking layers and, immensely high electron mobility.
