文摘

The structure and local organization of new proton conducting ionic liquids (PCILs) obtained by reactingalkylamine with various acids were deciphered by complementary 1- and 2-D heteronuclear NMR experiments.One the one hand, PFG NMR yielded the self-diffusion coefficients of the PCIL components (and thusinformation on their possible concerted translational motions), while on the other hand, ¹³C, ¹H, and ¹⁵N, ¹Hcorrelation and intermolecular Overhauser experiments gave insight into the nature of protonic species andion-pairing behavior.
