Parallel triplet formation pathways in a singlet fission material
Nature Communications, 2022 The singlet fission mechanism is still not relatively well understood, except for polyacenes. Here, the authors demonstrate that in diketopyrrolopyrrole supramolecular assemblies, both singlet fission and intersystem crossing can simultaneously happen.

Elucidating complex triplet-state dynamics in the model system isopropylthioxanthone
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

Optical properties of Ge-oxygen defect center embedded in silica films [PDF]
, 2007 The photo-luminescence features of Ge-oxygen defect centers in a 100nm thick Ge-doped silica film on a pure silica substrate were investigated by looking at the emission spectra and time decay detected under synchrotron radiation excitation in the 10-300

Intersystem Crossing in Diplatinum Complexes
The Journal of Physical Chemistry A, 2016 Intersystem crossing (ISC) in solid [(C4H9)4N]4[Pt2(μ-P2O5(BF2)2)4], abbreviated Pt(pop-BF2), is remarkably slow for a third-row transition metal complex, ranging from τISC ≈ 0.9 ns at 310 K to τISC ≈ 29 ns below 100 K. A classical model based on Boltzmann population of one temperature-independent and two thermally activated pathways was previously ...

Intersystem Crossing Processes of Acridine [PDF]
Bulletin of the Chemical Society of Japan, 1977 Abstract The T1(π, π*)→T3(π, π*) absorption of acridine has first been observed at about 985 nm in ethanol. Temperature dependences of the fluorescence lifetime and the triplet yield of acridine were investigated in poly(vinyl alcohol) film, and it was found that the intersystem crossing from the first excited singlet state S1(π, π*) to ...
