Case I: Metal acetylacetonate Example 1: Nickel First, the Ni±oleylamine complexwas prepared by reacting 0.52 g of nickel(acetylacetonate)2[Ni(acac)2, Aldrich Chemical Co., 95%] and 2 mL of oleyla-mine (Aldrich Chemical Co., technical grade, 80%) at 100Cunder an Ar atmosphere. The resulting metal-complex solu-tion was injected into 5 g of triphenylphosphine (TPP, AldrichChemical Co., 99%) at 215C.…

Case 1: Antiferromagnetic Cobalt Oxide Nanooctahedra The organic−inorganic interface determines the crystalline growth directions of the nanoparticles by means of a dynamic solvation of these surfactants in solution, which generally contain electron-donating groups to allow coordination to electron-poor metal atoms at the nanocrystal surface. Nano Lett. 2014, 14, 2, 640–647 Figure 1. EEL spectra (h)…

Case 1: Cobalt Oxide Nanoparticles [prof. Joon T. Park’s group] Example 1: The fcc CoO solid nanoparallelepipeds, are reduced by the oleylamine surfactant to form fcc Co hollow nanoparallelepipeds A green slurry of [Co(acac)3] (0.10 g, 0.28 mmol) in neat oleylamine (9.24 mL) was heated at 135 °C for 5 min. Immediately after dissolution, the reaction mixture was flash-heated to 200 °C. After…
