Previous investigations of chemically functionalized anthracene derivatives have revealed unique self-assembly properties on Cu(111); however, like other studies of ordered films, they arrange into compact patterns dictated by short range intermolecular interactions or into straight molecular rows. Here we would like to report an oxygen derivative that - although it adsorbs on the surface analogous to other anthracene derivatives - exhibits a novel self-assembled porous network with a pore size of ~50Å. This hexagonal pattern reflects a balance between intermolecular attractions as well as long range repulsion.
