Molecular Trapping on Two-Dimensional Binary Supramolecular Networks

摘要

Molecular preferential adsorption on molecular patterned surfaces via specific intermolecular interactions provides an efficient route to construct ordered organic nanostruc-tures 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.
