Real-Time Sensing of Oxygen Molecules by Ultrathin Hybrid Filmsof Luminescent Iridium(III) Complexes and Clay Nanosheets

摘要

The quantitative determination of the oxygen concentration is essential to various practicalfields ranging from life sciences to environmental applications.1 Recently luminescentcyclometalated iridium(III) complexes (Ir(III)) have been applied as a sensing element for thispurpose.Ir(III) complexes are attracting a wide attention due to their highly emitting propertiesin a visible region.2 The previously reported sensing films were mostly prepared by the castingmethod.3
