Beautiful! Congratulations @pascalsci.bsky.social

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 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.

These golden flakes in Tatiana Munteanu’s flask caught her eye. While conducting research as a postdoc at the Interdisciplinary Nanoscience Center of Marseille, Munteanu worked on synthesizing phenazinium dyes like this pink compound: cen.acs.org/synthesis/Ch...

This week in Science, researchers report an artificial molecular motor that can twist a molecular thread to form a mechanically interlocked molecule. The approach creates opportunities to fabricate mechanically interlocked molecules with precise structural control.

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 🤯)
A joint study from CINaM (@univ-amu.fr) & CEISAM (Nantes Univ) labs, now OA in @orgchemfront.rsc.org:

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.

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!
