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.

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.

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 🤯)

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!

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!
