Petit rappel que les concours CNRS pour 2026 ouvrent dans 2 semaines, mais que c'est MAINTENANT qu'il faut rédiger votre projet de recherche.
Parce que vous avez mieux à faire entre Noël et le jour de l'an (si si, je vous assure)
Bravo Yoann, enjoy your next chapter in Lyon !
Je crois que je me vois, coin de la régie à gauche, à faire du stop avec les bigoudènes, oh !

Thanks Tatiana !
A tetranitroazacalixarene macrocycle captures cyanide reversibly via nucleophiloic aromatic substitution to form a metastable dianionic bis-Meisenheimer complex, with a color change of the solution from yellow to orange.
What began as an unexpected color change years ago led us to a rare discovery: a metastable macrocycle with two Meisenheimer adducts, fueled by cyanide and stabilized by H-bonds.

A colorfoul scheme of anionic coupled polymethine dyes and their neutral precursors, uncovering a range of exciting photophysical behaviors: including ESIPT, photoacid emission, and NIR pH-switching.
New chapter in the coupled polymethines story:
we explored anionic & neutral dyes, with exciting photophysics (e.g., pH-switching via spirocyclization of a dianionic species 🤯)

Picture of the end of the HDR defense of Yoann Cotelle with the jury.
Big congrats to Dr Yoann Cotelle (iSm2, Marseille) who brilliantly defended his HDR today, a great day for supramolecular chemistry, and a perfect reason to gather a remarkable jury !
Exciting research and now exciting news: Tatiana, who carried out most of this work, has just joined Bluesky!

Scheme of a far-red absorbing cationic benzoquinone diimine dye and plot of its absorption spectrum, with a picture of the dye dissolved in dichloromethane solution.
How far can we push quinones into the NIR while keeping them ultra-light?
Our latest dye, synthesized by Tatiana Munteanu (CINaM, @univ-amu.fr) and modeled by Carmelo Naim (CEISAM, Nantes Univ.), reaches nearly 700 nm with MW < 300 Da!

This is the cover of the Journal J. Org. Chem. from January 2025. The cover juxtaposes the molecular structures of your bis-zwitterionic macrocycles against a stunning mountainous landscape, creating a striking symmetry. The molecular orbitals and bonds seem to mirror the rugged peaks and valleys of the mountains, suggesting a connection between the natural world and the precision of molecular design.
Our latest work explores new reactivities of benzoquinone-monoimines, including the one-step synthesis of bis-zwitterionic macrocycles via transamination.

Historical development of Coupled Polymethine Dyes and notable structures.
Hi Bluesky, bringing some color your way !
To start, we dove into 60+ years of Coupled Polymethines research, piecing together the colorful puzzle of these remarkable dyes.
