Molecular rotors reorienting in times as short as 0.01 nanoseconds at 150K and endowed with minimal constraints ( E a=0.5 kcal mol ‐1 ) were realized in MOFs. This benchmark of motional flexibility, coupled with porosity, entailed unprecedented sensitivity to gases, such as CO2, which could modulate extensively rotor dynamics. Our results highlight how largely crystal dynamics are responsive to the gas environment. For more information see the Communication by A. Comotti, A. Maspero et al. on page 11210 ff.
