Abstract

Metal-organic frameworks (MOFs) represent a promising platform for gas storage and separation. In this work, adsorption of olefins in Zn-doped HKUST-1 metal-organic framework is explored with hyperfine spectroscopy. By means of electron-nuclear double resonance and hyperfine sublevel correlation spectroscopy, we detect the interaction between the electron spins of the Cu2+ sites of the MOF and the 1H nuclear spins of adsorbed C2H4 and C4H8. Further analysis of the measured spectra allows us to precisely locate the protons in the vicinity of the Cu2+ ions and thereby establish ensemble-averaged structural models of the olefin molecules adsorbed at the open metal sites of HKUST-1.
