TL;DR: Direct observation by x-ray diffraction of a photoinduced paraelectric-to-ferroelectric structural phase transition using monochromatic 100-picosecond synchrotron pulses in tetrathiafulvalene-p-chloranil indicates structural changes at the molecular level.
Journal ArticleDOI
Symmetry breaking and structural changes at the neutral-to-ionic transition in tetrathiafulvalene-p-chloranil.
M. Le Cointe,M. H. Lemée-Cailleau,Hervé Cailleau,Bertrand Toudic,Loïc Toupet,G. Heger,F. Moussa,P. Schweiss,K. H. Kraft,Norbert Karl +9 more
TL;DR: The structural aspect of the temperature-induced neutral-to-ionic transition in the mixed-stack charge-transfer complex TTF-p-chloranil is directly analyzed using results obtained from neutron-scattering experiments as discussed by the authors.
Journal ArticleDOI
Structural phase transition in polyphenyls. IV. Double‐well potential in the disordered phase of p‐terphenyl from neutron (200 K) and X‐ray (room‐temperature) diffraction data
TL;DR: KITAIGORODSKY, A. I., HOTSYANOVA, T. L. as discussed by the authors, RIETVELD, H. M. and STRUCHKOV, YU.
Journal ArticleDOI
Elastically driven cooperative response of a molecular material impacted by a laser pulse.
Roman Bertoni,Maciej Lorenc,Hervé Cailleau,Antoine Tissot,Jérôme Laisney,Marie-Laure Boillot,Laurentiu Stoleriu,Alexandru Stancu,Cristian Enachescu,Eric Collet +9 more
TL;DR: A self-amplified responsiveness in a spin-crossover material during its delayed volume expansion is demonstrated and it is shown that elastically driven cooperativity triggered by a light pulse offers an efficient route towards the generation and stabilization of photoinduced phases in many volume-changing materials.
Journal ArticleDOI
Sequential Activation of Molecular Breathing and Bending during Spin-Crossover Photoswitching Revealed by Femtosecond Optical and X-Ray Absorption Spectroscopy.
Marco Cammarata,Roman Bertoni,Maciej Lorenc,Hervé Cailleau,Sergio Di Matteo,Cindy Mauriac,Samir F. Matar,Henrik T. Lemke,Matthieu Chollet,Sylvain Ravy,Claire Laulhé,Jean-François Létard,Eric Collet +12 more
TL;DR: Combined femtosecond x-ray absorption performed at LCLS X-FEL and optical spectroscopy reveal that the structural stabilization of the photoinduced high-spin state results from a two step structural trapping.
