| Abstract: | A crystalline nanoporous molecular network was tailored by supramolecular assembly of pentacene and F16CuPc on Cu(100). The structure and self‐assembly mechanisms of the pure and binary layers were analyzed by STM. F16CuPc films and mixed layers of pentacene/F16CuPc in a ratio of 2:1 show two enantiomorphic chiral domains with high structural order in contrast to pentacene which exhibits no long‐range order in pure films. A model of the epitaxial relationship on Cu(100) is given, which suggests C? F???H bonding as a possible driving force for the bimolecular self‐assembly in addition to the still strong interaction between the substrate and the organic bilayer. |
