Singlet fission is a photophysical reaction in which a singlet excited electronic state splits
into two spin-triplet states. Singlet fission was discovered more than 50 years ago, but the …

When many of the currently largest chemical companies were founded about 150 years ago,
textile dyes constituted their first products. Interestingly, while most of the utilized colorants …

Conspectus The active layer in a solution processed organic photovoltaic device comprises
a light absorbing electron donor semiconductor, typically a polymer, and an electron …

When an assembly of two or more molecules absorbs a photon to form a singlet exciton, and
the energetics and intermolecular interactions are favourable, the singlet exciton can rapidly …

Abstract D‐π‐A type 4‐((9‐phenylcarbazol‐3‐yl) ethynyl)‐N‐dodecyl‐1, 8‐naphthalimide
(CZNI) with a large dipole moment of 8.49 D and A‐π‐A type bis [(4, 4′‐1, 8 …

Singlet fission is a process in which a singlet exciton converts into two triplet excitons. To
investigate this phenomenon, we synthesized two covalently linked 5-ethynyl-tetracene (ET) …
