The Missing Link Crystallized From The Ionic Liquid 1-Ethyl-3-Methylimidazolium Tosylate: Bis-Aqua-(P-Toluenesulfonato-O)-Europium(Iii)-Bis-P-Toluenesulfonate Dihydrate, Si-Fu Tang, Anja V. Mudring
The Missing Link Crystallized From The Ionic Liquid 1-Ethyl-3-Methylimidazolium Tosylate: Bis-Aqua-(P-Toluenesulfonato-O)-Europium(Iii)-Bis-P-Toluenesulfonate Dihydrate, Si-Fu Tang, Anja V. Mudring

Bis-aqua-(p-toluenesulfonato-O)-europium(III)-bis-p-toluenesulfonate-dihydrate (1) was synthesized and structurally characterized. The crystal structure contains eight-coordinate europium(III) atoms. One oxygen atom from p-toluenesulfonate and seven aqua ligands form a slightly distorted square antiprism around Eu(III). A variety of O−H···O and intermolecular C−H···O hydrogen bonds link the asymmetric units into a two-dimensional layer, and these layers are further assembled into a three-dimensional supramolecular structure through intermolecular C−H···O hydrogen bonds and edge-to-face C−H···π interactions. The compound represents the structural missing link between the well-known lanthanide (Ln) tosylate (Tos) hydrates [(Ln(H2O)9](p-Tos)3(H2O) with noncoordinating tosylate and [Ln(H2O)6(p-Tos)2](p-Tos)2(H2O)3 where two tosylate groups coordinate to the lanthanide cation. It is …

[C12mim]3[DyBr6] (C12mim = 1-dodecyl-3-methylimidazolium) represents a new material with interesting luminescent behavior as well as mesomorphic and magnetic properties. The compound was found to show thermotropic liquid crystalline behavior and forms smectic mesophases which were investigated by hot-stage polarizing optical microscopy and differential scanning calorimetry. The emission color of [C12mim]3[DyBr6] can be tuned from white to orange-yellow by the choice of the excitation wavelength. Sample excitation with λex = 366 nm leads to the blue-whitish luminescence from the imidazolium cation itself. With λex = 254 nm the common Dy(III) emission is observed which mainly arises from the 4F9/2 → 6H13/2 …

1,3-Didodecylimidazolium salts have been prepared as first representatives of a new class of ionic liquid crystals (ILCs), showing thermotropic liquid crystalline behaviour in an extended temperature range below 70 °C. Remarkably strong non-Newtonian viscosity behaviour was found for the liquid-crystalline state of these ILCs.
