Environment-responsive upconversion based on dendrimer-supported efficient triplet-triplet annihilation in aqueous media

We report dendrimer complexes which can show triplet-triplet annihilation-supported upconversion from visible light to UV light in aqueous solutions. The Pt complex of octaethylporphyrin as a sensitizer and anthracene as an emitter were accumulated into the water-soluble dendrimers.
