Outline of Final Research Achievements

By using cyclometalated iridium(III) complexes as an emitting element, photo-responsive molecular devices for sensing oxygen gas was manipulated. A thin film was prepared by hybridization with clay minerals. In such a film, luminescent Ir(III) complexes were hybridized with clay minerals in order to enhance robustness and reliability. As a result, nanometer-thick hybrid films were constructed by applying the modified Langmuir-Blodgett method. The achievement of multi-emitting properties in response to oxygen pressure has been demonstrated.
