Fig. 2. Heteronuclear correlation (HETCOR) spectra for assignment of 1H chemical shifts and determination of the protonation state and intermolecular binding modes of the oligodynablocks. (a) The carbonyl region of the 1H–13C dipolar HETCOR spectrum of DMA2(CO2). (b) Full 1H–15N solid-state refocused INEPT spectrum of DMA2(CO2)*; eDUMBO-1221H homonuclear decoupling was applied during t1 evolution to obtain high 1H resolution.71 (c) Corresponding identified intermolecular binding modes.
