Supramolecular coordination networks of metal polycarboxylate complexes

Supramolecular Complexes and Supramolecular Catalysts Formed by Molecular Assembly of Multinuclear Metal Complexes in Aqueous Solutions

Metal-coordination-driven mixed ligand binding in supramolecular bisporphyrin tweezers.

Mg(II)bisporphyrin has been used as an efficient host for the selective binding of guest ligands. In the presence of heterogeneous guest pairs, 2-aminopyrimidine/pyrazine and 2-aminopyrimidine/1,4-dioxane, 2-aminopyrimidine is bound selectively inside the bisporphyrin cavity whereas pyrazine/1,4-dioxane is bound outside to produce 1D mixed ligand polymers. UV-vis, (1)H NMR spectra and X-ray str...

Cucurbit[8]uril-based supramolecular polymers: promoting supramolecular polymerization by metal-coordination.

Linear supramolecular polymers were obtained in aqueous solution by employing cucurbit[8]uril-based host-guest interaction as the driving force. Water-soluble monomers were prepared through direct metal-coordination. The rigid and bulky terpyridine-Fe linker can effectively enhance the monomer's solubility and suppress its cyclization, thereby promoting supramolecular polymerization.

Stability of 47Sc-complexes with acyclic polyamino-polycarboxylate ligands

The aim of this study was to evaluate acyclic ligands which can be applied for labeling proteins such as monoclonal antibodies and their fragments with scandium radionuclides. Recently, scandium isotopes (47Sc, 44Sc) are more available and their properties are convenient for radiotherapy or PET imaging. They can be used together as "matched pair" in theranostic approach. Because proteins denatu...

Architecture of supramolecular metal complexes for photocatalytic CO2 reduction: ruthenium-rhenium bi- and tetranuclear complexes.

We study the electrochemical, spectroscopic, and photocatalytic properties of a series of Ru(II)-Re(I) binuclear complexes linked by bridging ligands 1,3-bis(4'-methyl-[2,2']bipyridinyl-4-yl)propan-2-ol (bpyC3bpy) and 4-methyl-4'-[1,10]phenanthroline-[5,6-d]imidazol-2-yl)bipyridine (mfibpy) and a tetranuclear complex in which three [Re(CO)3Cl] moieties are coordinated to the central Ru using th...
