Design and Synthesis of Push−Pull Chromophores for Second-Order Nonlinear Optics Derived from Rigidified Thiophene-Based π-Conjugating Spacers
Jean-Manuel Raimundo,Philippe Blanchard,Nuria Gallego-Planas,Nicolas Mercier,Isabelle Ledoux-Rak,Rolland Hierle,Jean Roncali +6 more
TL;DR: In this paper, two series of push-pull chromophores built around thiophene-based π-conjugating spacers rigidified either by covalent bonds or by noncovalent intramolecular interactions have been synthesized and characterized by UV−vis spectroscopy, electric field induced second harmonic generation (EFISH) and differential scanning calorimetry.
Journal ArticleDOI
Push–pull chromophores based on 2,2′-bi(3,4-ethylenedioxythiophene) (BEDOT) π-conjugating spacer
Jean-Manuel Raimundo,Philippe Blanchard,Pierre Frère,Nicolas Mercier,Isabelle Ledoux-Rak,Rolland Hierle,Jean Roncali +6 more
TL;DR: In this paper, a red shift of the absorption maximum accompanied with a large increase of the quadratic nonlinear optical susceptibility was observed in push-pull NLO-phores.
Journal ArticleDOI
Synthesis, Spectral, Structural, Second-Order Nonlinear Optical Properties and Theoretical Studies On New Organometallic Donor−Acceptor Substituted Nickel(II) and Copper(II) Unsymmetrical Schiff-Base Complexes
Alexander Trujillo,Mauricio Fuentealba,Mauricio Fuentealba,David Carrillo,Carolina Manzur,Isabelle Ledoux-Rak,Jean René Hamon,Jean René Hamon,Jean Yves Saillard,Jean Yves Saillard +9 more
TL;DR: A rationalization of the structural, electronic, and redox properties of the title compounds is provided, based on a theoretical investigation at the density functional theory (DFT) level.
Journal ArticleDOI
Submicrometer 3D structures fabrication enabled by one-photon absorption direct laser writing
Mai Trang Do,Thi Thanh Ngan Nguyen,Qinggele Li,Henri Benisty,Isabelle Ledoux-Rak,Ngoc Diep Lai +5 more
TL;DR: Different aspects of the direct laser writing based on ultralow one-photon absorption (LOPA) technique are investigated and compared with the TPA technique, showing several advantages, such as simplicity and low cost.
Journal ArticleDOI
Linear and nonlinear optical properties of cationic bipyridyl iridium(III) complexes: tunable and photoswitchable?
Vincent Aubert,Lucie Ordronneau,Muriel Escadeillas,J. A. Gareth Williams,Abdou Boucekkine,Esther Coulaud,Claudia Dragonetti,Stefania Righetto,Dominique Roberto,Renato Ugo,Adriana Valore,Anu Singh,Joseph Zyss,Isabelle Ledoux-Rak,Hubert Le Bozec,Véronique Guerchais +15 more
TL;DR: High negative EFISH μβ values are observed upon photocyclization, suggesting that the quadratic NLO response is dominated by the MLCT/L'LCT processes, rather than by the intraligand excited states localized on the substituted bipyridine ligand.
