Abstract: A metal organic framework comprising zinc (II) ions and second metal ions, such as iron (II) ions, cobalt (II) ions, and copper (II) ions as nodes or clusters and coordinated 1,3,5-benzenetricarboxylic acid struts or linkers between them forming a porous coordination network in the form of polyhedral crystals that are isostructural to HKUST-1. Transmetallation processes for producing the metal organic frameworks, as well as methods for applications of the metal organic frameworks as catalysts, specifically catalysts for the oxidation of cyclic hydrocarbons, such as toluene, cyclohexane, and methylcyclohexane.

Abstract: Gold nanoparticles functionalized with thiolated, bidentate Schiff base ligands. The Schiff base ligands form a ligand monolayer surrounding and binding to the surface of a gold nanoparticle core through Au—S linkages. The functionalized gold nanoparticle composites have a spherical shape, an average diameter of 7-15 nm and a narrow particle size distribution. Methods of assessing these functionalized gold nanoparticle composites as fluorescent probes in Fe(III) chemosensing applications, methods of preparing the functionalized gold nanoparticle composites and methods of detecting Fe(III) ions with the same are also provided.
