The robust synthetic flexibility of metal-organic frameworks (MOFs) offers a promising class tailorable materials, for which the ability to tune specific physicochemical properties is highly desired. This achievable only through thorough description consequences chemical manipulations both in structure and dynamics. Magic angle spinning solid-state NMR spectroscopy many modalities this pursuit, particularly dynamic studies. Herein, we employ separated-local-field approach show how intraframework modifications MOF UiO-66 heavily modulate evolution organic ring moiety over several orders magnitude.
