Geometry Controls Confined Water Dynamics in Lipidic Mesophases

open access: yesAngewandte Chemie, EarlyView.
An archaeal‐inspired lipidic mesophase allows precise control of interfacial curvature and water‐channel connectivity. Combining structural, thermodynamic, and ultrafast spectroscopies, we reveal that curvature governs the structure and reorientation dynamics of confined water, establishing a molecular‐level link between topology and dynamics in soft ...
