21/6/2018· Calcium-based metal-organic frameworks (MOFs) are low cost and have bio-compatible metal centers, but the Ca local environment is often poorly understood. Although very challenging due to 0.135 % natural abundance, 43 Ca solid-state NMR at a high magnetic field of 21.1 T can probe the local structure of the Ca center in MOFs, investigate the presence of guests, and monitor phase changes.
