Confined condensation synthesis and magnetic properties of layered copper hydroxide frameworks

초록

We present a confined condensation technique for the fabrication of layered copper hydroxide frameworks from lamellar copper-organic assemblies with long alkyl chains through the selective introduction of hydroxo bridging ligands. The complete transformations of two different lamellar copper-organic assemblies, Cu(C12H25SO4)(2)-4H(2)O (Cu-DS) and Cu-2(C11H23CO2)(4)- 2H2O (Cu-lau), into the corresponding layered copper hydroxide frameworks, Cu-2(OH)(3)(C12H25SO4) (Cu-OH-DS) and Cu-2(OH)(1.8)(C11H23CO2)2.2 (Cu-OH-lau), were achieved via confined condensation. The magnetic properties of both lamellar copper-organic assemblies, Cu-DS and Cu-lau, and both layered copper hydroxide frameworks, Cu-OH-DS and Cu-OH-lau, were investigated. It was found that drastic changes in the magnetic properties arise as a result of the confined condensation process.
