a) Amide region of the ¹H‐¹³C FSLG HETCOR spectrum of the pure polymer recorded with a contact time of 1.5 ms alongside the ¹³C NMR spectrum in CDCl₃ (full 2D spectrum in the Supporting Information). b) Comparison of the chemical shift (green) and line width (red) of the CH₃ group of the hydrophilic polymer block pMeOx for the pure polymer and the three formulations. c) and d) ¹H‐¹³C FSLG HETCOR spectra of CUR‐6‐P and CUR‐11‐P recorded at 14.1 T and 20 kHz MAS with a contact time of 5 ms alongside the vertical slices extracted as highlighted by the coloured bars. Coloured boxes indicate cross‐peaks originating from CUR–Pol intermolecular contacts. The 2D dataset of CUR‐2‐P can be found in the Supporting Information.
