Van ‘t Hoff Institute for Molecular Sciences argue that modern-day chemists need to broaden their horizons and consider the effects of chemistry “beyond the reaction vessel and the fume hood.” In order to combat ever-worsening environmental crises, and to achieve real sustainability, chemistry needs to develop a combined focus on efficiency, safety, and circularity.
Admittedly, over the past decades more and more sustainable synthetic methods have become available, minimizing or even eliminating the use of hazardous substances and waste. But, Flerlage and Slootweg rhetorically ask, is chemistry there yet? Their answer: “Not at all!” As an example, they refer to perfluorocubane, a molecule that in 2022 was designated ‘Molecule of the Year’. Its synthesis might be a stellar achievement, and there will probably be potential future applications. But its structure, containing multiple carbon-fluorine bonds, suggests that perfluorocubane will persist in the environment and bioaccumulate.
Flerlage and Slootweg argue that modern chemistry needs to take such environmental concerns to heart, and right from the start. They even go so far as to consider it unethical to develop chemistry that will lead to chemical pollution. They call for an end to poorly designed compounds, in particular “forever chemicals” such as per- and polyfluorinated alkyl substances and brominated flame retardants.
