Lanthanide-doped nanoparticles (LnNPs) have become an important class of fluorophores for advanced biosensing and bioimaging. LnNPs that are photosensitized by surface-attached antenna ligands can possess exceptional brightness. However, their functional

Four isostructural metal organic frameworks (MOFs), namely [Co 6(HipO)6]·6H2O (1), [Mn 6(HipO)6]·6H2O (2), [Cd 6(HipO)6]·6H2O (3) and [Zn 6(HipO)6]·7H2O (4) (H3ipO = 2-hydroxyisophthalic acid), were synthesized and structurally characterized. They have a 3D (4,6)-connected framework based on [24-MC-6] metallacrown clusters ([24-MC-6]-based MOFs). The arrangements of the 24-MC-6 metallacrown SBUs show a regular change indicated by the orientation of their symmetry axes, resulting in a special dense packing mode different from other [24-MC-6]-based MOFs. The analysis of SQUID measurements reveal that compound 1 displays the dominant antiferromagnetic exchanges in 300-10 K between the adjacent Co(ii) ions and a ferromagnetic-like behavior at lower temperatures, whereas compound 2 shows an antiferromagnetic interaction between the adjacent Mn(ii) ions. Compound 1 exhibits a magnetocaloric effect (MCE) with the resulting entropy change (-ΔSm) of 15.20 J kg-1 K-1 for ΔH = 50 kG at 6 K, which is the highest value among the cobalt-based MOFs with MCE reported so far. The luminescence properties of compounds 3 and 4 were studied, both of them exhibit photoluminescence in the solid state at room temperature which can be ascribed to intraligand π→π* transitions.

The new Ru complex 8 containing the bio-inspired ligand 7 was successfully synthesized and characterized. Complex 8 efficiently catalyzes water oxidation using CeIV and RuIII as chemical oxidants. More importantly, this complex has a sufficiently low overpotential to utilize ruthenium polypyridyl-type complexes as photosensitizers. Water splitting: A bio-inspired ligand containing imidazole and phenol functionalities has been synthesized. The corresponding Ru complex (1) could efficiently catalyze water oxidation under visible light illumination using Ru polypyridyl-type complexes as photosensitizers. Copyright
LUMINESCENT MACROCYCLIC LANTHANIDE COMPLEXES
-
Page/Page column 74, (2008/12/05)
The present invention provides a novel class of macrocyclic compounds as well as complexes formed between a metal (e.g., lanthanide) ion and the compounds of the invention. Preferred complexes exhibit high stability as well as high quantum yields of lanthanide ion luminescence in aqueous media without the need for secondary activating agents. Preferred compounds incorporate hydroxy-isophthalamide moieties within their macrocyclic structure and are characterized by surprisingly low, non-specific binding to a variety of polypeptides such as antibodies and proteins as well as high kinetic stability. These characteristics distinguish them from known, open-structured ligands.

The complex [Cu2(1)2]2+ (1=1,3-bis(1-methyl-1H-benzimidazol-2-yl)benzene) undergoes slow oxidation by dioxygen in DMF solution to give the hydroxylated product [Cu 2(2-H)2]2+ (2=2,6-bis(1-methyl-1H-benzimidazol- 2-yl)phenol) characterized by an X-ray crystal-structure analysis. The oxidation occurs much faster when CuII is mixed with 1 in the presence of H2O2, with 80% hydroxylation observed within a few minutes. The mononuclear complex formed with 1-methyl-2-phenyl-1H-benzimidazole (3) shows no hydroxylation under these conditions. It is concluded that the hydroxylation requires the presence of a ligand capable of stabilizing a binuclear species, but no special coordinative activation of the copper is required.

The present invention provides novel compounds of the Formula (I): A-B, its prodrug forms, or pharmaceutically acceptable salts thereof, wherein A represents a saturated, unsaturated, or a partially unsaturated bicyclic heterocyclic ring structure, and B represents an aryl or a heteroaryl group. Preferred compounds of the present invention comprise a benzimidazole or indole nucleus. The compounds of this invention are inhibitors of serine proteases, Urokinase (uPA), Factor Xa (FXa), and/or Factor VIIa (FVIIa), and have utility as anti cancer agents and/or as anticoagulants for the treatment or prevention of thromboembolic disorders in mammals.
