Diazocines are bridged azobenzenes with phenyl rings connected by a CH2–CH2 group.
Despite this rather small structural difference, diazocine exhibits improved properties over …

One of the major limitations of solid-state perovskite-sensitized photon upconversion to date
is that the only annihilator successfully paired with the perovskite sensitizer has been …

Singlet fission in organic semiconductors provides an important opportunity to study high-
spin states in electronically coupled chromophores. Photoexcitation of oriented, crystalline …

To reveal the relationship between molecular packing and singlet fission (SF) property is
necessary for developing efficient SF materials, yet it remains unclear. Herein, we …

The singlet fission (SF) process is a promising route to overcome the Shockley and Quiesser
