Synthesis of an anionic derivative of the terpyridine ligand

A procedure for preparing a 4′-triphenylborate-substituted derivative of the 2,2′:6′,2″-terpyridine ligand is described. Such a modification renders the terpyridine ligand anionic, which enables unique design possibilities for coordination chemistries involving metal ions relative to the unsubstituted parent ligand. Proof-in-principle that this new ligand can coordinate to transition metals was provided through the synthesis of a novel nickel complex.

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.

Affecting the Catalytic Activity of the Known [Ru(tpy)(bpy)(OH2)]2+ Complex in Water Oxidation by Utilization of a Hangman Ligand

[Ru(tpy)(bpy)(OH2)]2+ (bpy = 2,2′-bipyridine, tpy = 2,2′;6′,2'-terpyridine) is the archetype of many known single-site ruthenium complexes used for catalytic water oxidation. Its efficiency is likely influenced by installing a proton-donor/acceptor functionality in proximity to the catalytic site because the reaction mechanism is believed to occur by nucleophilic attack of a water molecule on a high-valent metal-oxo species assisted by hydrogen-bonding interactions. We present herein the results of a study of a new metal complex based on the hangman motif that possesses a carboxylic functional group close to the ruhenium center. This catalyst was synthesized in very good yield and fully characterized. We discovered that its catalytic activity was in fact hampered by the presence of the functional group. Further investigations revealed a strong dependence of the catalytic performance not only on the solvent, but also on the counter ion and other additives used. A ruthenium-based hangman complex has been synthesized and tested in catalytic water oxidation. Experiments using cerium(IV) ammonium nitrate as oxidant in aqueous solution revealed that a mismatched pH retards oxygen evolution in comparison with the unfunctionalized parent compound.

Terpyridine-porphyrin hetero-pacman compounds

The two different coordination spheres afforded by Pacman architectures offer cooperativity derived from two different metal centers. A modular strategy is developed to produce a hetero-Pacman scaffold featuring a porphyrin and terpyridine for metal-ion binding. A double Suzuki reaction was employed to first attach a terpyridine moiety to a xanthene backbone and then attach a porphyrin. The new hetero-Pacman scaffold has been characterized and all building blocks have been isolated and structurally characterized. The principle objective to incorporate different metal centers was confirmed by isolating a trinuclear complex comprising two porphyrinic units and a bis(terpyridine)-iron unit. The compounds described herein expand the Pacman scaffold concept by allowing for the incorporation of a terpyridine-metal complex proximate to a porphyrin-cofactor active site for small-molecule activation. Pacman fever: A hetero-Pacman scaffold featuring a porphyrin and a terpyridine coordination pocket for metal-ion binding was produced by a modular strategy (see figure). A double Suzuki reaction gave a metalloligand with a free terpyridine coordination site. Subsequent reaction with iron triflate resulted in the isolation of a trinuclear compound. Copyright
