A new host molecule consists of four terpyridine groups as the binding sites with zinc(II) ion and a copillar[5]arene incorporated in the center as a spacer to interact with guest molecule was designed and synthesized. Due to the 120 ° angle of the rigid aromatic segment, a cross-linked dimeric hexagonal supramolecular polymer was therefore generated as the result of the orthogonal self-assembly of metal-ligand coordination and host-guest interaction. UV/Vis spectroscopy, 1H NMR spectroscopy, viscosity and dynamic light-scattering techniques were employed to characterize and understand the cross-linking process with the introduction of zinc(II) ion and guest molecule. More importantly, well-defined morphology of the self-assembled supramolecular structure can be tuned by altering the adding sequence of the two components, that is, the zinc(II) ion and the guest molecule. In addition, introduction of a competitive ligand suggested the dynamic nature of the supramolecular structure. Orthogonal self-assembly: A fluorescent cross-linked supramolecular polymer was constructed by the orthogonal self-assembly of metal-ligand coordination and host-guest interaction. The well-defined morphology of the self-assembled supramolecular structure can be tuned by altering the adding sequence of the two components, that is, zinc(II) ion and the guest molecule (see figure).

The 2D adsorption of molecules onto insulating surfaces is of increasing interest for future devices in emerging technologies such as molecular electronics, sensors, single-molecule optics, and on-surface synthesis. However, most attempts to stabilize molecular structures on these substrates have been hampered by weak molecule-surface interactions and so there is a need to develop organic molecules bearing suitable grafting groups. We report herein the synthesis of a series of molecules designed to be physisorbed onto alkali halide crystalline surfaces. They comprise a rigid central benzene or triphenylene core bearing, respectively, two or six alkyl ether chains terminated by cyano, carboxylic, α-amino acids, or 1,2,3-triazoles as anchoring groups. Two series of molecules designed for grafting onto KBr or NaCl surfaces have been prepared. The molecules comprise a rigid central benzene or triphenylene core bearing, respectively, two or six alkyl ether chains terminated by cyano, carboxylic, α-amino acids, or 1,2,3-triazoles as anchoring groups.
