Abstract
Zn solid-state NMR suffers from low sensitivity, limiting its ability to probe the Zn surroundings in MOFs. We report a breakthrough in overcoming challenges in Zn 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.
