Chemists from the National University of Singapore (NUS) have developed innovative materials that can harness both singlet and triplet excited states for efficient, metal-free photocatalysis.

The singlet-triplet gap (ΔEST) in organic molecules governs key photophysical and photochemical processes, including fluorescence, phosphorescence and intersystem crossing. At its core, this energy ...

Singlet fission, where an electronically excited singlet on one chromophore converts into a doubly excited state on two, has gone from a curiosity in organic photophysics to a potential pathway for ...

Applying hydrostatic pressure as an external stimulus, Tokyo Tech and Keio University researchers demonstrate a new way to regulate singlet fission (SF), a process in which two electrons are generated ...

Singlet fission is a photoconversion process that generates a doubly excited, maximally spin entangled pair state. This state has applications to quantum information and computing that are only ...

A photosensitizer (PS) is a chemical species that initiates a reaction upon absorption of light. Although the chemical compositions and practical applications of PS' differ widely, they all follow the ...
