A new preprint is available, Patrick’s first manuscript as first author: The role of excited-state character, structural relaxation, and symmetry breaking in enabling delayed fluorescence activity in push-pull chromophores.
Well done, Patrick!
Photochemistry
Excited-state symmetry breaking
A recent study led by Zoltan Szakacs and Eric Vauthey from the University of Geneva explores excited-state symmetry breaking in donor-acceptor-donor systems. The associated paper just appeared in PCCP: Excited-state symmetry breaking in 9,10-dicyanoanthracene-based quadrupolar molecules: the effect of donor-acceptor branch length
The main idea behind this work is to use symmetry-selection rules and the associated forbidden transitions to probe how inversion symmetry is broken during the photodynamics. See [JPCL 2021, 12, 4067] for an initial discussion of the idea.
Fluorescence Activity of Fingerprinting Reagents
A new paper on the photochemistry of fingerprinting reagents, led by L. Hunnisett and P. Goddard at Loughborough, just appeared in J. Chem. Phys.: Mechanistic Insight into the Fluorescence Activity of Forensic Fingerprinting Reagents. The paper investigates the reason for the different fluorescent activities observed in chemically related fingerprinting reagents.
