Environment‐Dependent Ultrafast Photodynamics of Aurone Derivatives for the Photoprotection of Agrochemicals

open access: yesChemPhotoChem, Volume 9, Issue 6, June 2025.
Five derivatised aurones were synthesised via a green approach for potential application as photoprotectants for agrochemicals. Their long‐term and ultrafast photodynamics, in solution and on a wax surface, were investigated through steady state and femtosecond transient electronic absorption spectroscopy techniques, revealing significant differences ...
