Abstract
Triplet‐triplet annihilation upconversion (TTA‐UC) technology could convert low‐energy light into high‐energy light, and it is a very promising one of the upconversion technologies due to its non‐coherent excitation light, low required excitation optical power density and sensitizer/annihilator flexible adjustability. The application of TTA‐UC into photocatalysis could not only broaden the range of solar energy spectrum utilization, but also bring mild reaction conditions and higher product yields via avoiding the side reaction. However, the detailed catalytic mechanism of TTA‐UC is unclear. Therefore, in this review, we summarized and classified TTA‐UC photocatalytic chemical reactions in terms of mechanism.
