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

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 ...

Sky Blue and Yellow Cluster Light-Emitting Diodes Based on Asymmetric Cu4I4 Nanocubes
Research, 2022 Controllably optimizing excited-state characteristics is crucial for luminescent nanoclusters but remains a formidable challenge. Herein, we report an effective “ligand-induced asymmetrization” strategy for constructing thermally activated delayed ...

Triplet-state phosphoryl biradicals
Synthetic Metals, 1995 The first example of triplet-state phosphoryl diradicals is reported. Photoinduced dissociative electron capture of two diastereoisomeric m-phenylenebis(ph0sphinic ch1oride)is in a glassy toluene matrix at 130 K using an electron-rich olefin affords the corresponding hosphoryl monoradicals and triplet-state diradicals in a 5:2 ratio.

Applications and Prospects for Triplet–Triplet Annihilation Photon Upconversion
CHIMIA, 2018 Triplet–triplet annihilation photon upconversion (TTA-UC) is a photophysical process in which the energy of two photons are combined into a single photon of higher energy.
