%X We investigate the dynamic behavior of long guest rodlike particles immersed in liquid crystallinephases formed by shorter host rods, tracking both guest and host particles by fluorescence microscopy.Counterintuitively, we evidence that long rods diffuse faster than short rods forming the one-dimensionalordered smectic-A phase. This results from the larger and noncommensurate size of the guest particles ascompared to the wavelength of the energy landscape set by the lamellar stack of liquid slabs. The long guestparticles are also shown to be still mobile in the crystalline smectic-B phase, as they generate their ownvoids in the adjacent layers.
