Conformationally Switchable Copper(I) Complexes Amplify BODIPY Triplet Photosensitization.
With its potential to surpass the Shockley-Queisser limit, triplet-triplet annihilation upconversion (TTA-UC) has been heralded as a powerful solution in direct solar-to-fuel energy conversion. TTA-UC combines low-energy photons to generate high-energy states for photocatalysis. TTA-UC requires a triplet photosensitize...
