| Outline of Final Research Achievements |
We developed a new methodology, triplet energy migration-based photon upconversion, instead of conventional molecular diffusion-based photon upconversion. The regular chromophore arrangements was achieved in metal-organic framework, and the triplet state of this acceptor assembly was sensitized by surface-modified sensitizer molecules. This new material design allowed the maximization of photon upconversion efficiency at very weak excitation intensity such as sunlight for the first time.
