In episode 6 of the Člankarnica podcast, Dr. Petra Utroša from the Department of Polymer Chemistry and Technology at the National Institute of Chemistry explains how photoacids and photobases control pH in reactions. She discusses their study, which reveals that the chemical reactivity of these compounds doesn’t always align with their light absorption, an insight with significant implications for their use. The study was published in Chemistry – A European Journal: https://chemistry-europe.onlinelibrary.wiley.com/doi/10.1002/chem.202400820.The expert opinion on this paper was provided in the preview: https://www.cell.com/matter/abstract/S2590-2385(24)00338-2__________ In the Člankarnica podcast, together with researchers from the National Institute of Chemistry, we present interesting and accessible explanations of their latest discoveries, published in prestigious scientific journals.
