“…Luminescent lanthanide complexes have attracted intense research interest due to their very narrow emission bands and large Stokes shifts, see: Wang et al (2009); Bunzli & Piguet (2005); Stein & Wurzberg (1975). For amide-type open-chain ligands, see: Liu et al (2009); Yi et al (2007); Hamann et al (2004).…”

There is a need to prepare a new series of amide type ligands to further widen the scope of research on the chemical and physical properties of lanthanide complexes.…”

In the title compound, C36H40N5O6 +·NO3 −·2C2H5OH, the nitrate anion is disordered over the two orientations of equal occupancy while the solvent molecule reveals large displacement parameters. The cation is formed by protonation of the N atom of a secondary amine in the middle of the flexible chain and the whole compound has crystallographically imposed C-2 symmetry with the crystallographic b axis. An O atom of the nitrate anion links the acidic H atoms of the cation via N—H⋯O hydrogen bonding. In addition, neighbouring cations are connected by intermolecular N—H⋯O hydrogen bonds and π–π interactions between the benzamide groups of the cations [centroid–centroid distance = 4.000 (3) Å], forming a chain along [001]. The ethanol solvent molecules are arranged on the side of the chain through O—H⋯O hydrogen bonds.

“…Through the last decade, considerable research effort has been made on the study of luminescent lanthanide complexes [17,18] due largely to the applications of such materials in biomedical and optical technologies [19]. Since the discovery of their industrial uses, the relationship between research and these elements has been kept alive until today when many high-technology applications of lanthanidecontaining materials such as energy-saving lighting devices and responsive luminescent stains heavily rely on the brilliant and pure-color emission of lanthanide ions [19][20][21][22][23]. In fact, the complexes formed with these ions have considerable advantages: easily recognizable, line-like emission spectra, long lifetimes, and relative insensitivity to photo-bleaching [22].…”

Polymers from natural sources are particularly useful as biomaterials for medical devices applications. In this study, the results of characterization of a gelatin network electrolyte doped with europium triflate (Eu(CF 3 SO 3 ) 3 ) are described. The unusual electronic properties of the trivalent lanthanide ions make them well suited as luminescent reporter groups, with many applications in biotechnology. Samples of solventfree electrolytes were prepared with a range of guest salt concentration. Materials based on Eu(CF 3 SO 3 ) 3 were obtained as mechanically robust, flexible, transparent, and completely amorphous films. Samples were characterized by thermal analysis (thermogravimetry analysis (TGA) and differential scanning calorimetry (DSC), electrochemical stability, scanning electron microscopy (SEM), and photoluminescence spectroscopy.

“…Specific bands with maxima at 1533, 1896, and 2556 cm −1 were found in the Raman spectra of the AcEu (0.1 M) solution, which are obviously associated with AcEu luminescence [44]. There is also a Raman band of stretching vibrations of water in the region of 3000-3800 cm −1 (Figure 1A).…”

Study of the Effect of Europium Acetate on the Intermolecular Properties of Water

This paper investigates the effects of europium acetate and intensive stirring on the intermolecular properties of water in solutions. To do this, we studied aqueous solutions of europium acetate in a wide range of concentrations, which were prepared by serial dilution using a microfluidic unit. Water and similarly prepared water dilutions were used as controls. Raman spectroscopy and infrared (IR) spectroscopy were applied to assess the features of hydrogen bonds formed in the studied solutions. Using Raman spectroscopy, it was shown that intermolecular binding is stronger in solutions of europium acetate of 10–1 M and 10–3 M than in water controls. On the contrary, solutions of europium acetate at a concentration of 10–10 М and some lower concentrations demonstrate weaker hydrogen bonding than in the respective water dilutions, which was shown by both methods. Such differences were observed even in solutions with a calculated concentration of europium acetate below 10–24 M. When comparing water with control dilutions of water, it was established that intermolecular binding is different (stronger or weaker) in high dilutions of water than in water not subjected to the dilution procedure. This indicates that the dilution process itself significantly influences the properties of water in solutions. Additionally, the paper discusses the energy state of water molecules in the studied solutions.
