1. An organic light emitting device, comprising:

  • an anode;

    a cathode; and

    at least one organic layer disposed between the anode and the cathode;

    the organic layer comprising a reversibly reducible metal complex of a redox active metal center and at least one ligand;

    whereinin a reduced state, an extra electron is localized on the metal center, and wherein the metal complex is of Formula I
