The non-Debye relaxation behavior of amphidynamic zirconium MOF is identified by broadband dielectric spectroscopy and a low barrier is found despite rotator-framework interactions.
Significance and Impact
The work provides an approach for analyzing complicated dynamics of dipolar rotor arrays in a porous framework and paves the way for future design of dielectric materials.
