A 2D porous network has been realized by self-assembly of porphyrin modules on a silver surface, as reported by Diederich and co-workers on p. 275. The so-formed pores are able to host single fullerene molecules and mediate long-range interactions between such carbon guests, resulting in the formation of large supramolecular chains and islands. The cover shows a scanning tunnelling microscopy image of several single C60 molecules (large green protrusions) hosted in the 2D porous network. As indicated by the molecular model, each pore is formed by the symmetric arrangement of three porphyrin molecules and the fullerene guest is located exactly in the center of the cavity.
