Molecular-level characterization of the structure and the surface chemistry of periodic mesoporous organosilicates using DNP-surface enhanced NMR spectroscopy

We present the molecular level characterization of a phenylpyridine-based periodicmesoporous organosilicate and its post-functionalized organometallic derivatives through the fast acquisition of high quality natural isotopic abundance 1D C-13, N-15, and Si-29 and 2D 1H-C-13 and 1H-Si-29 solid-state NMR spectra enhanced with dynamic nuclear polarization.
