Outline of Final Research Achievements |
The molecular devices for photo-sensing oxygen gas are manipulated by using cyclometalated iridium(III) complexes as an emitting element. In the attempts, an ultra-thin film hybridizing a luminescent Ir(III) complex with a clay mineral (synthetic saponite) was prepared by applying the modified Langmuir-Blodgett method. Such hybridization resulted in the enhancement of robustness of films and the reliability of sensing. By use of artificially controlled layering, the interlayer distance between the donor and the acceptor was changed to tune energy transfer efficiency. The results indicate the possibility of developing of multi-emitting device, efficient energy harvesting or chiral sensing on clay surface.
