22 dyes later, we changed the plan and finally report a bunch of new dicationic and neutral AcceptorâDonorâAcceptor dyes with neat electrochemical & photophysical properties. A joint study from CINaM (@univ-amu.fr) & CEISAM (@univ-amu.fr) labs, now in J. Org. Chem. (@acs.org): shorturl.at/C7iM3
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)

Post-doctoral position at CEISAM lab in Nantes ! Join to synthesize near-infrared dyes and design next-gen solar cells, within the Connect Talent TRANSCEND project funded by RĂ©gion Pays de la Loire, Nantes MĂ©tropole & @cnrs.fr. Deadline: Sept. 23rd Apply here: emploi.cnrs.fr/Offres/CDD/U...
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 study from CINaM (@univ-amu.fr) & CEISAM (Nantes Univ), now OA in @angewandtechemie.bsky.social : tinyurl.com/a65eekm8
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 đ€Ż) A joint study from CINaM (@univ-amu.fr) & CEISAM (Nantes Univ) labs, now OA in @orgchemfront.rsc.org: tinyurl.com/58kudd4j
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! Follow her for more on quinones and dyes: @tatianamunteanu.bsky.social
Simon Pascal@pascalsci.bsky.social · 2y agoHow 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!

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. Check out our review in The Chemical Record: shorturl.at/aYwg
