Overcoming challenges in 67Zn NMR: a new strategy of signal enhancement for MOF characterization

Chem Commun (Camb). 2023 Apr 27;59(35):5205-5208. doi: 10.1039/d3cc00716b.

Abstract

67 Zn solid-state NMR suffers from low sensitivity, limiting its ability to probe the Zn2+ surroundings in MOFs. We report a breakthrough in overcoming challenges in 67Zn NMR. Combining new cryogenic MAS probe technology and performing NMR experiments at a high magnetic field results in remarkable signal enhancement, yielding enhanced information for MOF characterization.
