New sulfonic acid functionalized ionic liquids (SAFILs) with bis(trifluoromethylsulfonyl)imide anions were synthesized. These ionic liquids are strong Brønsted acids and can solubilize metal oxides. Water-immiscible SAFILs were used as organic phases in solvent extraction studies.

Методами спектроскопии ИК- и ЯМР Н С с использованием теоретических расчетов (программы ChemDrawUltra, Marvin, ACD/Labs) изучены спектральные характеристики L-цистеинсульфоновой кислоты (L-cysSOH) в растворах виде частично протонированной формы (SO)CHCH(NH)COO-(рН=3) депротонированного иона(SO-)CHCH(NH)COO-(рН=10). Установлено, что отличие от спектров кислоты, спектрах не наблюдается сильного с...

The designed aromatic amide discotic molecule with sulfonic acid groups at its periphery exhibits a hexagonal supramolecular columnar liquid crystalline phase, which leads to the achievement of anisotropic ionic conductivity through macroscopically aligning the ionic channels.

Time-resolved EPR spectra of UV-irradiated Nafion reveal the formation of spin-polarized excited triplet states and allow the detection of photoinduced triplet-triplet energy transfer processes through hydrogen bonds between water and sulfonic acid groups.

A new sulfur-containing guanidino derivative, halichondria sulfonic acid (1) showing anti-HIV-1 activity, and halistanol trisulfate (2) with anti-tumor activity have been isolated from the marine sponge Halichondria rugosa Ridley & Dendy collected in the Chinese Southern Sea. The structure of 1 was elucidated by analysis of spectroscopic and crystal data.
