New insights into solvent-induced structural changes of 13C labelled metal–organic frameworks by solid state NMR.

Selective ¹³C-labelling of carboxylate carbons in the linker molecules of flexible metal–organic frameworks (MOFs) makes solid-state NMR spectroscopy very powerful to investigate solvent-induced local structural changes as demonstrated by ¹³C and ¹H NMR spectroscopy on the pillared layer MOF DUT-8(Ni). Selective identification of polar solvent–node interactions becomes feasible. [ABSTRACT FROM AUTHOR]
