Osaka Metropolitan University scientists have successfully synthesized 3-hydroxybutyrate, a raw material for poly-3-hydroxybutyrate (PHB)—a strong, water-insoluble, biodegradable plastic used for packaging materials—from acetone and CO2. With a visible light-driven catalytic system utilizing sunlight and two biocatalysts, the researchers achieved a high conversion yield of about 80%. Mimicking natural photosynthesis, this study artificially reproduced a light reaction involving sunlight and a dark reaction fixing CO2 to synthesize the raw material for PHB. The finding is expected to contribute to solving the plastic waste problem and to reducing CO2.

- New HPHAC analogues with an embedded nonbenzenoid aromatic ring have been synthesized. - The newly synthesized HPHACs exhibit multistep redox properties and their dicationic species showed an aromatic nature based on macrocyclic conjugation. - Methylation on the nonbenzenoid aromatic ring resulted in the development of "antiaromaticity".

An Ehime University group led by Dr. Ishibashi and Prof. Asahi reported that when a nanosecond laser pulse was irradiated to diarylethene nanoparticles which show the photo-induced isomerization reaction from the colored closed-form to the colorless open-form, the ring-opening reaction was at most 80 times more effective than that in the solution phase. The amplification could be well explained as a ‘photosynergetic effect’ coupled with nanoscale photothermal conversion and a photochemical reaction. There are very few reports of such a nanosecond laser pulse induced amplified photochemical reaction in nanoparticles, indicating a new photoenergy conversion method.
