Pushing the boundaries of environmentally friendly chemical production entails using novel approaches and technologies to reduce environmental impact while maintaining efficiency. A group of forward-thinking researchers from the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) has made significant progress in the complex world of molecular chemistry.
Their primary concern? Azaarenes are unique molecular puzzle pieces that are essential to many everyday products, ranging from environmentally friendly agrochemicals to essential medicines. The CABBI team demonstrated a novel method of modifying these molecules, a game-changing discovery that holds promise for new industrially relevant chemical reactions and sustainable energy solutions.
The use of photoenzymatic systems is central to their research. In layman’s terms, it’s like arming nature’s tiny workers, enzymes, with a flashlight, allowing them to assemble or repair molecular structures in previously unimaginable ways. These scientists discovered novel chemical reactions that were previously thought to be out of reach by harnessing the power of light.
With our novel approach to azaarenes and the use of enzymatic hydrogen atom transfer, we’re not just pushing boundaries in chemistry. We’re laying the groundwork for a more sustainable, innovative future. Our research has expanded the eco-friendly production toolkit and has the potential to catalyze breakthroughs in agrochemicals and beyond.

The study, published in Nature Chemistry, was conducted by researchers from the University of Illinois Urbana-Champaign. The lead authors are CABBI Conversion Theme Leader Huimin Zhao, Professor of Chemical and Biomolecular Engineering (ChBE), biosystems design theme leader of the Carl R. Woese Institute for Genomic Biology (IGB), and Director of the NSF Molecule Maker Lab Institute at Illinois; and Maolin Li, a Postdoctoral Research Associate with CABBI, ChBE, and IGB.
Azaarenes, seemingly minuscule in the vast universe of chemistry, nonetheless play a monumental role. They are the building blocks in a plethora of compounds, influencing even the DNA in our cells. But the challenge has always been in their manipulation.
Researchers discovered a way to intricately modify these molecules without collateral damage thanks to the team’s development of an ene-reductase system – a specialized molecular toolkit using the ene-reductase enzyme that Zhao’s lab has used in previous studies.
One of their most notable accomplishments was mastering enantioselective hydrogen atom transfer. Molecules, like gloves, frequently come in left- and right-handed versions, or enantiomers. The team’s method enables them to target and adjust either version with unrivaled precision. Furthermore, they could make those precise adjustments from a distance using a remote stereo control.
For CABBI and the bioenergy sector, this discovery is a game-changer. Biofuels and bioproducts — energy and products derived from plant material instead of non-renewable resources like petroleum — represent a greener and more sustainable future. The team’s research has expanded the range of chemical reactions and bioproducts that can be made efficiently.
Asymmetric photocatalysis, a revolutionary technique that ensures consistency in these reactions, was also introduced in the study. This has the potential to open up new opportunities for producing biofuels and bioproducts from a broader range of biomass feedstocks, which is directly aligned with CABBI’s goals and the broader DOE mission to advance sustainable energy and product solutions.
“With our novel approach to azaarenes and the use of enzymatic hydrogen atom transfer, we’re not just pushing boundaries in chemistry,” Zhao went on to say. “We’re laying the groundwork for a more sustainable, innovative future.” Our research has expanded the eco-friendly production toolkit and has the potential to catalyze breakthroughs in agrochemicals and beyond.”
Beyond the lab, the potential for real-world applications is enormous, from pioneering sustainable energy to pioneering safer agricultural chemicals. Bioenergy and bioproduct advancements can lead to economic growth by creating new industries, jobs, and products for consumers, as well as potentially more affordable energy sources. The research can reduce pollution and environmental degradation by promoting sustainable and efficient production methods, resulting in cleaner air and water for communities.
As the world grapples with environmental challenges and the pressing need for sustainable solutions, discoveries like these, according to Li, illuminate the path forward.
“As a postdoctoral researcher on this project, I’ve become intimately acquainted with the complexities of azaarenes and their potential.” Unraveling the mysteries of remote stereo control and witnessing the transformative potential of our discoveries has been truly thrilling. This study is about more than just the nuances of chemical reactions; it is also about the future of sustainable energy. “I’m looking forward to seeing where this journey takes us next,” Li said.
