| Outline of Final Research Achievements |
Triplet-triplet annihilation-based photon upconversion (TTA-UC), low-energy photons being converted into higher ones by a bimolecular mechanism involving a sensitizer and two emitter molecules, have attracted increasing attentions as promising methods for energy conversion from low-energy excitation to higher energy light. In this study, the quest of microenvironments aiming at developing efficient UC has been carried out, in which it was found that the addition of metal complexes into the system enabled multi-color emission. Alternatively, near-infrared absorbing dyes as a candidate of sensitizers was successfully synthesized.
