Lanthanide-mediated triangular cationic assemblies: structural and physico-chemical properties.
نویسندگان
چکیده
This contribution investigates Ln(III) complexes formed with a small ditopic ligand, L1, and their structural, thermodynamic and photophysical properties. The spectrophotometric and NMR titrations evidence the triangular assemblies [Ln(3)(L1-H)(3)](6+) at stoichiometric conditions and their properties are discussed in relation to L2-containing analogues. In addition, the dinuclear species, [Ln(2)(L1-H)](5+), is observed with an excess of metal.

متن کاملBook review of “Lanthanide metal-organic frameworks”
Metal-organic frameworks (MOFs) are chemical systems comprising organic molecules coordinated to metal ions or clusters to form one-, two-, or three-dimensional structural arrangement (Figure 1). The use of lanthanide (Ln) ions results in a specific class of Ln-MOFs possessing unique physico-chemical properties owing to a large atomic magnetic moment, strong spin-orbital coupling, high coordina...

متن کاملProducion of Nanoparticle Assemblies by Electro-Spraying and Freeze-Drying of Colloids: A New Method to Resolve Handling Problem of Nanoparticles
To resolve handling problem of nanoparticles, due to their small size, a new methodology of electro-spraying and freeze-drying was developed for colloidal nanoparticles of silica and titania to transform them to solid macro-scale nanoparticle assemblies. The assemblies were then redispersed in an aqueous system to investigate the effect of formulation of original solutions and the process ...
