“…[1][2][3][4] This makes ILs interesting for applications where molecular solvents are not suitable or inefficient, for example due to their high vapor pressure. [5][6][7][8] As a result, the evaluation of ILs as device components in chemical sensors, fuel cells, batteries, etc. is currently being pursued, with promising initial results.…”

Transparent, ion-conducting, luminescent, and flexible ionogels based on the room temperature ionic liquid (IL) 1-butyl-3-methylimidazolium bis(trifluoromethane sulfonyl)imide [Bmim][N(Tf) 2 ], a PtEu 2 chromophore, and poly(methylmethacrylate) (PMMA) have been prepared. The thermal stability of the PMMA significantly increases with IL incorporation. In particular, the onset weight loss observed at ca. 229 C for pure PMMA increases to 305 C with IL addition. The ionogel has a high ionic conductivity of 10 À3 S cm À1 at 373 K and exhibits a strong emission in the red with a long average luminescence decay time of s ¼ 890 ms. The resulting material is a new type of soft hybrid material featuring useful thermal, optical, and ion transport properties.

“…[17,20,24] Herein, we report the syntheses of a new class of waterfree pentanitratoeuropate(III) ionic liquids and their coordination structures, thermal stabilities, and luminescence properties (Scheme 2). The imidazolium-based cations were utilized to form ionic liquids with low melting points and high thermal stabilities.…”

“…Most of the reported research has focused on solid materials or their solutions, [23] and reports of Eu-based ionic liquids are rare (Scheme 1). [17,20,24] Though the coordination numbers of the Eu III ions in the few ionic liquids are considered to be 6-9, [17,20,24] the local Eu environments are uncertain and there is no detailed structural information. Furthermore, the N-donor ligands in these ionic liquids may lower their thermal stabilities compared with those of Eu III -based ionic liquids composed of O-donor ligands.…”

A series of luminescent ionic liquids based on pentanitratoeuropate(III) anions combined with imidazolium cations, namely, 1,2,3-trimethylimidazolium (6)}, were synthesized. These complexes were characterized by NMR and IR spectroscopy as well as elemental analysis. They exhibit high thermostability and wide liquidus ranges of more than 300°C. Colorless plate crystals of 1 were isolated, and the crystal structure was determined by single-crystal X-ray

“…12,15,[17][18][19] Incorporating lanthanide ions as an anion into ionic liquids is an effective way to increase the concentration of lanthanides. 13,14,16 An alternative approach to increase the solubility of metal salts is to use task-specific ionic liquids (TSIL) bearing a complexing moiety.…”

The addition of organic ligand (β-diketone or heterocyclic compound) to the europium (III)-containing ionic liquid resulted in bright luminescent soft materials with the molar ratio of europium/ionic liquid (IL)/ligand being 1:3:1 that exhibit bright red light under UV lamp. The luminescent properties such as emission features and lifetime of 5 D0 Eu3+ excited level are dependent on the organic ligands. The materials were characterized by FT-IR and luminescence spectroscopy. The data shows that at least parts of the ILs (carboxylic acid) are replaced with β-diketone ligand rather than the formation of europium complex with the molar ratio of Eu 3+ : IL: ligand being 1:3:1, while no ILs could be replaced by the heterocyclic ligand such as Bpy and Phen.
