Abstract
AbstractHerein, a detailed investigation of the adsorption and dynamics of C60 and C70 fullerenes hosted in a self‐assembled, two‐dimensional, nanoporous porphyrin network on a solid Ag surface is presented. Time‐resolved scanning tunneling microscopy (STM) studies of these supramolecular systems at the molecular scale reveal distinct host–guest interactions giving rise to a pronounced dissimilar mobility of the two fullerenes within the porphyrin network. Furthermore, long‐range coverage‐dependent interactions between the all‐carbon guests, which clearly affect their mobility and are likely mediated by a complex mechanism involving the Ag substrate and the flexible porphyrin host network, are observed. At increased fullerene coverage, this unprecedented interplay results in the formation of large fullerene chains and islands. By applying a lattice gas model with nearest‐neighbor interactions and by evaluating the fullerene‐pair distribution functions, the respective coverage‐dependent guest–guest interaction energies are estimated.
