A study was conducted to demonstrate the preparation and characteristics of a supramolecularly caged ionic iridium(III) complex [Ir(ppy) 2(Hpbpy)][PF6], where ppy is 2-phenylpyridine and Hpbpy is 6-phenyl-2,2'-bipyridine. The second complex was compared with the parent complex, [Ir(ppy)2(Hpbpy)][PF6] during investigations. It was demonstrated that the lifetime of a simple electroluminescent device employing air-stable electrodes and supramolecularly-caged complex, as the active component is more than 3000 hours at an average luminance of 200 cd m-2, while operating at a driving voltage of 3 volts. The large increase in lifetime was obtained, without sacrificing the device turn-on time.
