Fig. 3: Interfacial material and water dynamics are mediated through incorporation of flexible, hydrated surface linkers.
From: Interfacial dynamics mediate surface binding events on supramolecular nanostructures
a, Compounds (4)–(6) are spin-labeled (purple) aramid amphiphiles that are co-assembled into compounds (1)–(3) (Fig. 1a), respectively, to probe dynamics near surface-tethered chelators. b, Electron paramagnetic resonance (EPR) spectroscopy of indicated co-assemblies reveals an over three-fold enhancement in the rotational diffusion constant of probes on nanoribbon surfaces from OEG4-linker containing amphiphiles relative to those with no linker. Fits to each profile are shown with a black line and a 90% confidence interval to each reported diffusion constant is shown in parentheses. Curves are vertically offset for clarity.
