Template-based in situ fabrication and melamine sensing of bis(8-quinolinolato)zinc(II) complex nanorod arrays

Parallel polycrystalline bis(8-quinolinolato)zinc(II) complex nanorod arrays, with diameters in the range of 250-320 nm and length of 25 m, are in situ fabricated by liquid-liquid interfacial precipitation in the pores of porous anodic aluminum oxide membrane. The prepared nanorods show an enhanced photo- luminescence emission compared to submicron particles and can be used as a good melamine probe for easy and highly sensitive detection.

Adduct formation of zinc oxinate chelate with some nitrogen bases

Visible and u.v. spectra of zinc oxinate chelate in chloroform showed bathochromic shifts on addition of nitrogen bases.These shifts, large compared to those due to solvent effects alone, were attributed to adduct formation.From a quantitative evaluation of the data, the formation constants of what proved to be 1:2 adducts were determined.The stabilities of these adducts were found to increase in the order: neocuproin 2,2'-bipyridyl ethylenediamine = 1,10-phenanthroline.The formation of a very weak adduct in the case of neocuproin is attributed to the sterically hindering methyl groups ortho to nitrogen atoms in the molecule.

Preparation of 8-hydroxyquinoline complexes and application of 8-hydroxyquinoline complexes in prevention and treatment of plant diseases

The invention relates to the technical field of chemical pesticides, and discloses application of any compound of 8-hydroxyquinoline zinc complexes (Ya)-(Yj) in preparation of drugs for preventing orresisting sclerotinia rot of colza, botrytis cinerea, wheat scab and rice blast. Due to the fact that 8-hydroxyquinoline has wide biological activity, the complexes show huge potential in an antifungal aspect, and elemental zinc (Zn) has good bactericidal performance. The 8-hydroxyquinoline zinc complexes organically combine the biological activity of 8-hydroxyquinoline and the biological activity of Zn, and an activity test shows that the complexes show remarkable antibacterial activity can be developed as agricultural bactericides.

ZINC CHALCOGENIDES, DOPED ZINC CHALCOGENIDES, AND METHODS OF MAKING

A process of preparing a zinc chalcogenide includes providing a solution of 8-hydroxyquinoline; a zinc precursor; and a reaction solvent; isolating a precipitate from the solution; and calcining the precipitate to form the zinc chalcogenide. Additionally, a polymer composite may include a polymer, bis(8-hydroxyquinolinato)zinc, and elemental sulfur or bis(8-hydroxyquinolinato) z M, wherein M is a metal ion and the value of z is equivalent to the oxidation state of the metal ion.
