title: Molecular trapping on two-dimensional binary supramolecular networks.
abstract: Molecular preferential adsorption on molecular patterned surfaces via specific intermolecular interactions provides an efficient route to construct ordered organic nanostructures for future nanodevices. Here, we demonstrate the preferential trapping of second-layer molecules atop two-dimensional binary supramolecular networks, F(16)CuPc on DIP:F(16)CuPc and 6P:F(16)CuPc systems, respectively, through intermolecular π-π interactions. The formation of the second-layer supramolecular nanostructures, individual molecular dots or linear molecular chains, can be controlled by the underlying molecular networks.
