Metal-Ion Dynamic Nuclear Polarization NMR – A Novel Tool for Studying MOF-based Materials

Ilia B. Moroz – @IliaMoroz92

Can NMR probe host-guest interactions in MOFs? In theory yes, but an intrinsically low sensitivity of NMR is quite a limitation… What is the solution?

Host-guest interactions in MOFs are key to their performance in various applications. Solid-state NMR can probe these interactions, however, with limited sensitivity. I will demonstrate how endogenous metal-ion DNP can tackle this challenge, keeping MOF pores empty for guests, and discuss the effect of MOFs mobility and molecular O2 on the DNP efficacy.
