Fast intersystem crossing in the tetracene dimers as a source of “dark” state

AIP Advances, 2023
Tetracene (Tc) is a prototype material undergoing singlet fission (SF), the formation of a pair of triplet excitons from a singlet exciton. The tetracene dimer Tc2 is supposed to be a structural unit providing SF behavior.

Collective behaviours: from biochemical kinetics to electronic circuits [PDF]

, 2013
In this work we aim to highlight a close analogy between cooperative behaviors in chemical kinetics and cybernetics; this is realized by using a common language for their description, that is mean-field statistical mechanics.
