A matter of minutes: Dynamic nuclear polarization (DNP) is applied to enhance the signal of solid-state NMR spectra of metal–organic framework (MOF) materials. The signal enhancement enables the acquisition of high-quality 1D 13C solid-state NMR spectra, 2D 1H–13C dipolar HETCOR and 1D 15N solid-state NMR spectra with natural isotopic abundance in experiment times on the order of minutes.
