Rotor speed regulation In the hybrid walls of porous p-phenylenesilica can be ach-ieved by guest uptake and removal. A graduation from slow to ultrafast motional regimes {k = 104-108 s-1) can be experienced by the molecular rotors depending on guest nature and temper-ature, as detected by solid-state spin-echo 2H NMR spectroscopy (see picture).

Abstract
Rotor speed regulation In the hybrid walls of porous p-phenylenesilica can be ach-ieved by guest uptake and removal. A graduation from slow to ultrafast motional regimes {k = 104-108 s-1) can be experienced by the molecular rotors depending on guest nature and temper-ature, as detected by solid-state spin-echo 2H NMR spectroscopy (see picture).
