Elucidating complex triplet-state dynamics in the model system isopropylthioxanthone [PDF]
iScience, 2022 Summary: We introduce techniques for probing the dynamics of triplet states. We employ these tools, along with conventional techniques, to develop a detailed understanding of a complex chemical system: a negative-tone, radical photoresist for multiphoton

Revealing the contest between triplet-triplet exchange and triplet-triplet energy transfer coupling in correlated triplet pair states in singlet fission [PDF]
, 2021 Understanding the separation of the correlated triplet pair state 1(TT) intermediate is critical for leveraging singlet fission to improve solar cell efficiency. This separation mechanism is dominated by two key interactions: (i) the exchange interaction

Recent Development of Heavy Atom-Free Triplet Photosensitizers for Photodynamic Therapy
Applied Sciences, 2022 Photodynamic therapy (PDT) is an attractive method for cancer treatment. Triplet photosensitizers (PSs) are critical for this method; upon photoexcitation, efficient intersystem crossing (ISC) occurs for triplet PSs, the triplet-excited state of the ...

Direct Evidence of a Transition from Triplet Excitons to Hybrid Light-Matter States via Triplet-Triplet Annihilation [PDF]
, 2020 In the enclosed manuscript, we embed a triplet-triplet annihilator inaccessible molecule inside an optical cavity. The system reaches the strong coupling regime, and the formed polariton has a reduced energy compared to the molecular singlet excited ...
