Reactivity of Copper(I) Halides CuCl, CuI with Double Alkoxides MAl(iOPr)₄ (M = Na, K)

Abstract

The heterogeneous reaction between CuX (X = Cl–, I–) with alkali metal double alkoxides MAl(iOPr)4 (M = Na, K) for the synthesis of CuI containing single source precursor has been studied. The orange colored precursor obtained showed strong absorption in the UV region (235 nm) and photo luminescence emission band at 450 nm, which evidenced the formation of an adduct between the reactants. Controlled hydrolysis and decomposition of the gel yielded delafossite structured CuAlO2 along with some CuO.

Synthesis, Crystal Structures, and Thermolysis Studies of Heteronuclear Transition Metal Aluminum Alcoholates

“…[2][3][4][5] They can be applied in different synthesis strategies, like sol-gel, hydrothermal, CVD (chemical vapor deposition) or other thermolytic processes. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] The properties of ternary oxides can be modified in a broader range compared to binary oxides, since a second metal ion establishes another opportunity to modify the structural properties. Therefore, material properties for applications, such as semi-conductivity, magnetism or superconductivity, can be adjusted.…”

“…Although some of the heteronuclear aluminum alkoxides have been used as SSPs in sol-gel synthesis, systematic thermolysis studies are still rare. [7][8][9][10][11][12][13][14][15][16][17] Indeed, the thermolysis mechanism of [Zn{AlH 2 (OtBu) 2 } 2 ] was clarified during isotope tracing in mass spectrometry experiments and reported by Veith and co-workers, but the investigation of the solid residues depending on the included bivalent metal ion is still missing. [51] This work contributes to that topic as well as to the influence of the 2,2Ј-bipyridine co-ligand on the thermolysis properties.…”
