The cover picture shows a new and efficient method of n-stacking functionalization of carbon nanotubes. As described by J. S. Lauret et al. on p. 1667, this method is applied to the synthesis of a high-yield light-harvesting system combining single-wall carbon nanotubes and porphyrin molecules. This three-step method based on the swelling of the micelle surrounding nanotubes is displayed in the upper part of the picture. The lower part shows the efficient energy transfer from the photosensitized porphyrin molecule to the nanotube.
