Beautiful! Congratulations @pascalsci.bsky.social
A purplish pink dye sits with at the bottom of a round-bottom flask. Flakes of a golden film float on the dye’s surface and tiny glittering flecks stick to the flask’s walls.
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 illustration shows consecutive stages during operation of a molecular catenating machine.
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.

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 🤯)

😀 Merci pour la pub, Simon!
I’m following the colors, everywhere ☺️!
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!
