Supramolecular Assemblies of a Bis(terpyridine) Ligand and of its [2×2] Grid-type ZnII and CoII Complexes on Highly Ordered Pyrolytic Graphite

Supramolecular Coordination: Self-Assembly of Finite Two- and Three-Dimensional Ensembles

“…Similarly, adsorption of bis-terpyridine-based [2 × 2] grid-type Zn(II) and Co(II) assemblies on HOPG surfaces led to well-organized adlayers. 683,684 …”

Synthesis, structure and luminescence properties of zinc (II) complexes with terpyridine derivatives as ligands

“…Among the best studied complexes composed of 2,2 0 -bipyridine (bpy) and transition metals, Ru(bpy) 3 2+ is the most popular of all [20][21][22][23][24]. In the recent years, however, rapid development of supramolecular chemistry has shifted focus on 2,2 0 :6 0 ,2 00 -terpyridine (tpy), since this tridentate ligand offers more synthetic and structural advantages than the bidentate bpy [25][26][27][28][29][30]. Che [31] and coworkers have synthesized a new class of Zn-terpyridyl based polymer via self-assembly reactions, which are promising light-emitting materials for PLEDs.…”

Self-assembly of 2,6-dimethylpyridine on Cu(110) directed by weak hydrogen bonding

“…Strong hydrogen bonding is the most widely employed type of non-covalent interaction used in making self-assembled monolayers (SAMs) on surfaces [7][8][9][10]. Strong hydrogen bonds also frequently govern the interactions between biomolecules [10][11][12][13][14][15], the growth of organic molecular crystals [16,17], and many supramolecular structures [18][19][20], In contrast, weak hydrogen bonds are rarely used for the fabrication of self-assembled structures on surfaces [21][22][23]. Strong hydrogen bonds can occur between chemical groups in which there is an electronegative atom in the hydrogen donor group such as -COOH, -OH and -NH 2 , or an excess electron density in the hydrogen acceptor group.…”

“…The results presented here show the importance of weak hydrogen bonding in achieving supramolecular structure from molecules which cannot form strong intermolecular hydrogen bonds. Our findings confirm previous reports [21][22][23] for other adsorption systems indicating that desirable supramolecular architectures on surfaces are achievable even without involving strong hydrogen bonding interactions.…”
