Description
Maria Antonietta Dettori, Valeria Ugone, Davide Fabbri, and Paola Carta study how light reshapes a curry-linked compound, in a 2024 chemistry paper. The compound, dehydrozingerone, forms when curcumin breaks down. Under ultraviolet light, its shape can flip from one geometric form to the other.
The team shone UV light on the compound, on a doubled version of it, and on methylated variants of both. All produced flipped forms, with yields that depended on the solvent and the light's wavelength. The flipped plain compound and its dimer proved too unstable to purify. The methylated flipped forms, though, were isolated and fully mapped with magnetic and light-based methods, aided by computer models. The work adds detail on how light rewrites the shape, and likely the behavior, of curcumin-family molecules.
