The effect of electron polarization has been suggested to explain the exceptionally large length-to width aspectratio (more than 3000) in recently observed C60-based nanowires. The theoretical estimates performed in the present Lettershow that at room temperature the effect of electron polarization is negligibly small and, therefore, cannot become the drivingforce for nanowire growth along one preferential direction. Experimental measurements are in agreement with the theoreticalanalysis: the nanowires have been observed to emerge from the polar 1,2,4-trimethylbenzene and non-polar 1,3,5-trimethylbenzenesolution of C60, while no nanowires from polar toluene, 1,2,3-trimethylbenzene and non-polar benzene solutions could berecorded.
