| Outline of Final Research Achievements |
Because of the social demands for green innovation based on the strategy to reduce consumption of precious many elements, expectations for the next generation of photoelectric energy conversion devices using organic materials are significantly increasing. However, since the conversion efficiency of the organic electroluminescent diode or the organic solar cell is extremely low, it has not been put into practical use in full scale. Effective utilization of triplet excitons (triplet harvesting) holds the key to achieving ultra-high efficiency of organic electronic devices. In this research, we succeeded in raising the triplet fusion efficiency by spin angular momentum control in the transition state.
