- A triple-pore tessellated square array by a metal-hexagonal ligand with reinforced tetra-connectors
-
Tessellation of nine polygons into a 3 × 3 array is accomplished by the self-assembly of specifically designed hexaruthenium macrocycles containing a tetrapod ligand. Differing from the hexagon-containing bipod ligand, more connections lead to a giant dis

- Multi-terpyridyl metal organic ligand compound, five-membered flower ring-shaped supramolecule assembled thereby, and preparation
-
The invention discloses synthesis method of a five-membered flower cyclic supramolecule based on terpyridyl metal coordination. The supermolecule is a giant five-membered flower ring-shaped supermolecule formed by self-driving a ligand containing a plurality of terpyridyl and metal ruthenium and transition metal ions in a solvent, wherein the ligand and the transition metal can accurately react togenerate a single pentamer product without generation of other byproducts; then structural characterization and molecular weight determination are carried out on the ligand and a final assembly product through nuclear magnetism, mass spectrometry, scanning electron microscopy and other tests. The supermolecule has large molecular weight and good solubility, the molecular structure has symmetry and aesthetic properties, and gelation can be realized.

- Self-Assembly of Concentric Hexagons and Hierarchical Self-Assembly of Supramolecular Metal-Organic Nanoribbons at the Solid/Liquid Interface
-
In an effort to exert more precise control over structural features of supramolecules, a series of giant concentric hexagons were assembled as discrete structures using tetratopic terpyridine (tpy) ligands. In preparation of tetratopic ligand, pyrylium and pyridinium salts chemistry significantly facilitated synthesis. The key compounds were obtained by condensation reactions of pyrylium salts with corresponding primary amine derivatives in good yields. These discrete metallo-supramolecular concentric hexagons were fully characterized by NMR, ESI-MS, TWIM-MS, and TEM, establishing their hexagon-in-hexagon architectures. The combination of different tetratopic ligands also assembled hybrid concentric hexagons with increasing diversity and complexity. Furthermore, these concentric hexagon supramolecules with precisely controlled shapes and sizes were utilized as building blocks to hierarchically self-assemble supramolecular metal-organic nanoribbons (SMON) at solid-liquid interfaces. Ambient STM imaging showed the formation of long 1D SMON rather than 2D assembly on the basal plane of highly oriented pyrolytic graphite (HOPG) surface after simple dropcasting of the solution of preassembled concentric hexagons onto a freshly cleaved surface of HOPG. This wet chemical method based on self-assembly may offer simple, economical, and scalable routes to deliver complex materials.

- Performance of energy storage devices: potential areas for dendritic chemistry involvement
-
A compound consists of a fractal-like, plain or organometallic array useful for energy storage devices. A dendrimer useful in the synthesis of the fractal-like compound includes a single ligating moiety bound to a surface of each quadrant of the dendrimer. A method of making metallo-based (macro) molecules includes the steps of combining monomers selected from the group consisting of bipyridal- and terpyridal-based ligands with connecting metals and self assembling macrocycles wherein the monomes are interconnected by the metals.
