  • Patent number: 10010880
    Abstract: A new class of ligands derived from benzo[h]quinoline are described and these ligands are used to prepare several novel transition metal complexes. The complexes are preferably of the group VIII transition metals iron, ruthenium or osmium, with the benzo[h]quinolone ligands acting as tridentate ligands. The complexes described are proved to be very active catalysts for the reduction of ketones and aldehydes to alcohols, via hydrogen transfer and hydrogenation reactions. These compounds hence can be usefully employed as catalysts in said reduction reactions.

  • Patent number: 9890327
    Abstract: A phosphorescent transition metal complex especially suitable as sensor for hydrogen peroxide in cells, in particular in mitochondria in live cells, includes a metallic central atom, which is a transition metal, a first ligand with at least one pyridine ring, and a second ligand having at least one pyridine ring and at least one structural component selected from the group of 1,2-diketone moiety and an arylboronate moiety. A method for preparing the metal complex is also disclosed as well as a method of detecting hydrogen peroxide in cells by incubating cells with the transition metal complex. The metal complex shows advantageous intense and long-lived phosphorescence accompanied by exceptional cellular localization properties. The metal complex is highly photostable and highly selective towards hydrogen peroxide, thus, especially suitable for detecting mitochondrial H2O2.

  • Patent number: 9793499
    Abstract: The present invention provides an organic metal complex having high heat resistance while making it possible to realize electroluminescence with high quantum efficiency as a light-emitting material for organic electroluminescent (EL) element. The present invention relates to an organic iridium complex for an organic EL element, wherein a C—N ligand including a substituent of a tricyclic-based structure obtained by condensing a heterocyclic ring and two benzene rings, and a ?-diketone ligand composed of a propane-1,3-dione having two tert-butyl-substituted phenyl groups are coordinated with an iridium atom. The complex of the present invention has high heat resistance and contributes to lifetime prolongation of the organic EL element.
