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

Triplet-state phosphoryl biradicals [PDF]

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.

Long Excited-State Lifetimes in Three-Coordinate Copper(I) Com-plexes via Triplet–Triplet Energy Transfer to Pyrene-Decorated Isocy-anides [PDF]

There has been much effort to improve excited-state lifetimes in photosensitizers based on earth-abundant first-row transition metals. Copper(I) complexes have gained significant attention in this field, and in most cases, sterically-driven approaches ...

Heavy-atom effect on optically excited triplet state kinetics. [PDF]

PLoS ONE, 2017
In several fields of research, like e.g. photosensitization, photovoltaics, organic electroluminescent devices, dynamic nuclear polarization, or pulsed dipolar electron paramagnetic resonance spectroscopy, triplet state kinetics play an important role ...

Preparation and Photophysical Study of Rhodamine–Perylenebisimide Electron Donor–Acceptor Dyad/Triads Containing Flexible Linkers [PDF]

Molecules
We report the synthesis and characterization of the photophysical characterization of a series of rhodamine (Rho)–perylenebisimide (PBI) electron donor–acceptor dyad/triads containing flexible alkyl spacers (ethylene or hexylene chains).
