A new NMR DNP equipment in Marseille!
More infoThe Dynamic Nuclear Polarization technique allow to overcome the low sensitivity of the NMR technique thanks to the principle of the transfer of spin polarization from electrons to nuclei.
Find this new equipment at the Spectropole of the Federation Sciences Chimiques Marseille
Ultrafast Intersystem Crossing in Xanthone from Wavepacket Dynamics
J. Am. Chem. Soc. 2021, Accepted article
By means of quantum dynamic simulations, researchers of the CT team and the ICREA have established the photochemical mechanism of the atypical fast singlet-triplet transition in the excited state of Xanthone. They demonstrated the barrierless access to electronic state intersections. These intersections are close to minimum energy structures, allowing for such efficient non-radiative transition between singlets and triplets.
Monitoring Crystallization Processes in Confined Porous Materials by Dynamic Nuclear Polarization Solid-State Nuclear Magnetic Resonance
Journal of the American Chemical Society, 2021, 143, 6095−6103
Researchers from the SACS and CMO teams showed that solid-state NMR, combined with dynamic nuclear polarization (DNP), enables efficient detection of metastable, transient species formed at the early stages of crystallization processes occurring in pure water under nanoconfinement. The approach relies on a new class of polarizing agents composed of mesoporous silica materials with TEMPO radicals embedded in the walls of the material, developed at the ICR.

Guest exchange by a partial energy ratchet in water
Angew. Chem. Int. Ed. 2021, 60, 6617-6623
Landmark advances have recently allowed to mimic some mechanical aspects of biological molecular machines, but all the reported systems work in organic solvents. Researchers from the SREP, SACS, CROPS teams and University of Macau (Institute of Chinese Medical Sciences) have now described a partial energy ratchet working in water, suggesting that the macrocycles cucurbiturils could become prime components for the construction of advanced molecular machines.

Molecular Excited States Through a Machine Learning Lens
Nature Chemistry Reviews, 2021,
DOI: 10.1038/s41570-021-00278-1
This Review surveys a broad range of machine-learning applications in molecular excited-state research, including predicting molecular properties and searching for new optoelectronic materials. Pavlo O. Dral et Mario Barbatti (CT team) critically discuss machine-learning developments to track their progress, assess the current state-of-the-art, and highlight the critical issues to solve in the future.
