Artificial photosynthesis could be the key to environmentally friendly fuels. A research team led by @wengeroliver.bsky.social has developed a special molecule that can store four charges simultaneously under light irradiation. Wenger calls this molecule "an important piece of the puzzle."

Beautiful work!! Using fsTA, we discovered that charge separation mediates Energy Transfer in the long-lived⏳ iron complex-anthracene dyad designed and synthesized by Felix Glaser & @ludotroian.bsky.social - just published in ACS Central Science @pubs.acs.org 🥳 t.co/14xmp6kvHS

Thrilled to share our new JACS paper on anti-Kasha photoreactivity! We show that higher-lying excited states can drive electron transfer — opening new doors for photoredox catalysis. Huge thanks to @wengeroliver.bsky.social for the incredible mentorship! pubs.acs.org/doi/10.1021/...
