Synthesis, Characterization, and Magnetic Properties of Lanthanide-Containing Paramagnetic Ionic Liquids: An Evan’s NMR Study
The present study focuses on the synthesis and characterization of lanthanide-containing paramagnetic ionic liquids (ILs), [CnC1Im]3[MCl3X3] (n = 4, 6, and 8; M = Gd, Dy, and Ho; X = Br and Cl), derived from 1-alkyl-3-methylimidazolium anions. These paramagnetic ILs exhibit low vapor pressure, high thermal stability, physiochemical stability...
Synthesis and disassembly of an organometallic polymer comprising redox-active Co4S4 clusters and Janus biscarbene linkers
Here, we show for the first time that main-chain organometallic polymers (MCOPs) can be prepared from Janus N-heterocyclic carbene (NHC) linkers and polynuclear cluster nodes. The crosslinked framework Co4S4-MCOP is synthesized via ligand displacement reactions and undergoes reversible electron transfer in the solid state…
Microwave-assisted Synthesis of 1-(perfluorohexyl)-3-methylimidazolium iodide
A perfluorinated ionic liquid, 1-(perfluorohexyl)-3-methylimidazolium iodide, was synthesized via microwave reaction and compared to a non-fluorinated analog. Typically, the synthesis of fluorinated ionic liquids involves long reaction times and multiple steps. We have demonstrated a shortened synthesis and a more straightforward procedure…
Synthesis and properties of symmetrical N,N′-bis(alkyl)imidazolium bromotrichloroferrate(III) paramagnetic, room temperature ionic liquids with high short-term thermal stability
A series of paramagnetic ionic liquids (PILs) based on N,N′-bis(alkyl)imidazolium bromotrichloroferrate(III), [(Cn)2Im][FeCl3Br] (Im = imidazole; Cn = ethyl, butyl, hexyl, octyl, decyl, dodecyl), was prepared and compared against the more traditional [CnC1Im][FeCl3Br] (C1 = methyl) analogs.
