We use time-dependent density functional theory (TDDFT) to investigate the mechanism of
efficient triplet–triplet upconversion (TTU) in certain organic materials. In particular, we focus …

Triplet–triplet annihilation photon upconversion (TTA-UC) is a process where two low-
energy photons are converted into one higher-energy photon. A crucial component for an …

By virtue of the modularity of their structures, their tunable optical and magnetic properties,
and versatile applications, photogenerated triplet–radical systems provide an ideal platform …

Molecular aggregates are of interest to a broad range of fields including light harvesting,
organic optoelectronics, and nanoscale computing. In molecular aggregates, nonradiative …

Triplet‐triplet annihilation upconversion (TTA‐UC) has the potential to enhance photoredox
catalysis yield. It includes a sensitizer and an annihilator. Efficient and stable annihilators …

Two phenothiazine‐based electroactive compounds were synthesized by Buchwald‐
Hartwig cross‐coupling reaction. The compounds consist of pyridine‐or benzonitrile …

Triplet–triplet annihilation photon upconversion (TTA-UC) combines the energy of two
photons to provide one of higher energy that can be used to drive photochemical or …
