Abstract

Triplet-triplet annihilation-based photon upconversion (TTA-UC) of near-infrared (NIR) light to visible light in the solid-state remains as a great challenge due to the sensitizer aggregation that impedes the efficient triplet energy transfer. Herein, we successfully introduce a molecular sensitizer exhibiting direct singlet-to-triplet (S–T) absorption into a new emitter-based metal-organic framework (MOF) to achieve an efficient triplet sensitization and a NIR-to-visible TTA-UC in the solid-state.
