The Dawn of Green Chemistry: Researchers Unveil Tenfold Increase in Reaction Efficiency

The team surrounding Wenger and his postdoc Dr. Cui Wang determined this process of breaking out as a decisive step which restricts the energy performance and the speed of photochemical reactions.Radicals break freeAs long as the radicals stay in sets in the solvent cage, they can spontaneously react with one another back into the beginning materials. The longer the unwanted reverse response became, the more radicals were able to break out and the more energy effective and faster the preferred target items developed.Wang, who now holds the position of assistant professor at Osnabrück University, used 2 particular dyes in her research study, both of which absorb light and store its energy for a brief period before utilizing it to form pairs of radicals. In turn, he states that energy effectiveness is also a definitive requirement for the industrial use of photochemistry.Reference: “Cage escape governs photoredox reaction rates and quantum yields” by Cui Wang, Han Li, Tobias H. Bürgin and Oliver S. Wenger, 18 March 2024, Nature Chemistry.DOI: 10.1038/ s41557-024-01482-4.

The longer the undesirable reverse reaction became, the more radicals were able to break out and the more energy effective and quicker the preferred target products developed.Wang, who now holds the position of assistant professor at Osnabrück University, used two particular dyes in her research study, both of which take in light and store its energy for a short period before using it to form pairs of radicals. Due to the extra energy, the radicals were able to leave the solvent cage up to 10 times more effectively. In turn, he mentions that energy efficiency is likewise a definitive criterion for the industrial usage of photochemistry.Reference: “Cage escape governs photoredox reaction rates and quantum yields” by Cui Wang, Han Li, Tobias H.
