2. Ionic Liquid as a N,O-Donor Ligand-Based Extraction System Modifier: Establishing the Mechanism of Am(III)-Selectivity Increasing

Author

Gerasimov, M. A., Pozdeev, A. S., Evsiunina, M. V., Kalle, P., Yarenkov, N. R., Borisova, N. E., and Matveev, P. I.

Abstract

In this work, we studied the extraction systems for the separation f-elements based on the tetradentate N,O-donor ligand di(N-ethyl-4-ethylanilide) 2,2′-dipyridyl-6,6′-dicarboxylic acid (L). The organic phase of these systems was perspective fluorine-containing organic solvents–metanitrobenzotrifluoride (F-3), ionic liquid C4mimNTf2(IL), and their mixture. The increase of Am(III) selectivity in the presence of Ln(III) in cases of the diluent mixture was shown. The mechanism of the f-element complexation leading to the improved properties of the extraction systems was studied by UV–visible, Raman-spectroscopy, XRD-study, and density functional theory calculations.

5. Synthesis and Anion Binding Properties of 2,5-Diamidothiophene Polypyrrole Schiff Base Macrocycles

Author

Sessler, J. L., Roznyatovskiy, V., Pantos, G. D., Borisova, N. E., Reshetova, M. D., Lynch, V. M., Khrustalev, V. N., and Ustynyuk, Yu. A.

Abstract

Two easy-to-synthesize polypyrrolic 2,5-diamidothiophene Schiff base macrocycles are reported, along with their anion binding properties as determined via UV−vis spectroscopic titrations carried out in dichloroethane. There is a striking difference between the interactions with anions of the two macrocycles, a finding ascribed to differences in their rigidity. For example, the more flexible dipyrromethane-derived macrocycle displays a 1.2:1 hydrogen sulfate versus nitrate selectivity, while its more rigid bipyrrole-derived congener shows a 7.4:1 selectivity in favor to hydrogen sulfate.
