Fast molecular dynamics and large sorption capacity were combined in porous organic frameworks. The low-density, yet robust covalent architectures sustain extremely rapid rotational motion of the phenylene rings up to high temperatures. Porosity enables modulation of rotor dynamics by chemical stimuli: linear alkanes and iodine vapors, pervading the material, regulate rotor speed at will.
