“…Alvarez-Vicente et al prepared and characterized the [P 66614 ][LnCl 6 ] and [P 4444 ][LnCl 6 ] of the entire Ln 3+ series plus Y 3+ and Sc 3+ , as well as the [P 4448 ][LnCl 6 ] analogs for Ln = Ce, Nd, Sm, Tb, Dy, and Er [ 66 ]. The entire [P 66614 ][LnCl 6 ] series, with the longer alkyl chains in the phosphonium, is composed exclusively of room temperature ionic liquids, as commonly found for this cation [ 67 , 68 , 69 , 70 ], with melting points (m.p.) between −58 and −40 °C, with the exception of the La 3+ -IL at –1.6 °C.…”

Searching in the Web of Knowledge for “ionic liquids” AND “luminescence” AND “lanthanide”, around 260 entries can be found, of which a considerable number refer solely or primarily to europium (90%, ~234). Europium has been deemed the best lanthanide for luminescent applications, mainly due to its efficiency in sensitization, longest decay times, and the ability to use its luminescence spectra to probe the coordination geometry around the metal. The remaining lanthanides can also be of crucial importance due to their different colors, sensitivity, and capability as probes. In this manuscript, we intend to shed some light on the existing published work on the remaining lanthanides. In some cases, they appear in papers with europium, but frequently in a subordinate position, and in fewer cases then the main protagonist of the study. All of them will be assessed and presented in a concise manner; they will be divided into two main categories: lanthanide compounds dissolved in ionic liquids, and lanthanide-based ionic liquids. Finally, some analysis of future trends is carried out highlighting some future promising fields, such as ionogels.

“…37 Therefore, the introduction of rare earth ions enhances the magnetic susceptibility of M(P)ILs. 38 Meanwhile, lanthanide M(P)ILs show significant advantages in luminescent applications due to their high color purity, 39 high color intensity, 40 and long lifespan 41 of fluorescence. In our group, 42 we synthesized a perylene diimide (PDI)-based Gd-containing magnetic ionic liquid Per-6-Diimi[Gd(NO 3 ) 4 ].…”

The present study focuses on the synthesis and characterization of lanthanide-containing paramagnetic ionic liquids (ILs), [C n C1Im]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, and tunability, along with significant magnetic susceptibility, making them of interest in advanced material applications that may take advantage of neat liquids with magnetic susceptibility. Structural and physical properties were determined using FTIR, 1H NMR, DSC, and TGA. The room temperature density and viscosity of the iron paramagnetic ILs were also reported. Accompanying this report of paramagnetic IL products, we reintroduce and highlight Evan’s NMR technique, an accessible magnetic susceptibility measurement technique that can utilize any available proton NMR to characterize the magnetic susceptibility of ILs. This work demonstrates the robustness of Evan’s technique by demonstrating the ability to account for the IL water content, a common issue for hygroscopic materials, during the measurement of magnetic susceptibility. A detailed comparison of the ILs is presented, with dysprosium- and holmium-containing paramagnetic ILs exhibiting the highest magnetic susceptibility reported for mononuclear ILs reported to date. These materials have been studied with an eye on applications for mass transfer, eventually seeking to optimize magnetic susceptibility and viscosity using magnetic field gradients to move paramagnetic ILs carrying solute or heat. The study of paramagnetic ILs is important not only for understanding the magnetic properties of these materials but also for potential applications in areas such as magnetic resonance imaging, biomedicine, environmental remediation, and mass transfer. These unique materials have the potential to bring about new advances and technologies in the fields of materials science and analytical chemistry.
