A series of nine tetrakis lanthanide β-diketonate complexes of the type [C2mim][Ln(fod)4] (C2mim = 1-ethyl-3-methylimidazolium, fod = 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionate) were prepared, with yields above 80%, and their thermochem., photophys. and magnetic susceptibilities were evaluated. Thermochem. studies presented a rare and reversible conversion between two solid phases (polymorphism), characteristic of the [Ln(fod)4]– anion. Photophys. and magnetic studies revealed that Dy and Er presented the multifunctionality of being simultaneously SMMs and visible (Dy) or near infra-red (Er) emitters. The Nd, Ho and Tm analogs present characteristic emission bands in the NIR region (800-1200 nm), while Sm, Eu, Tb and Dy present emissions in the visible range. Magnetic susceptibility of Tb, Dy, Ho, Er and Tm salts were measured in the temperature range of 2-300 K, showing paramagnetic behavior, although with different regimes, with AC susceptibility measurements, at different frequencies in the range of 10-10 000 Hz, providing evidence of slow magnetic relaxation processes for Gd, Dy and Er analogs with SMM behavior. The experimental procedure involved many compounds, such as 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .
1-Ethyl-3-methyl-1H-imidazol-3-ium chloride(cas: 65039-09-0) is an imidazolium chloride ionic liquid that can be used as:a solvent as well as catalyst for the depolymerization of oak wood lignin; a solvent in the hydrolysis of hemicellulose (xylan) to xylose using Brønsted acid catalysts.Recommanded Product: 65039-09-0
