Identification of the Knoevenagel condensation reaction product on CNCs using solution‐state NMR spectroscopy in the [P4444][OAc]/[D6]DMSO electrolyte at 65 °C: a) 1H spectrum of the condensed cellobiose model compound in [P4444][OAc]/[D6]DMSO; b) diffusion‐edited 1H spectrum of the condensed CNCs showing the presence of key resonances; c) band‐selective TOCSY experiment showing correlations not extending over the introduced carbonyl; d) modification scheme.
