Application of optically active chiral bis- (imidazolium) salts as potential receptors of chiral dicarboxylate salts of biological relevance
Royal Society of Chemistry (2015)A family of chiral bis(imidazolium) salts derived from natural amino acids has been synthesized by a simple synthetic approach and the corresponding bis(trifluoromethylsulfonyl)imide salts have been shown to be room ... -
Cu2+, Zn2+, and Ni2+ Complexes of C2-Symmetric Pseudopeptides with an Aromatic Central Spacer
American Chemical Society (2016)Two new tetradentate C2-symmetric pseudopeptidic ligands derived from Val and Phe containing two amino and two amido groups and a central o-substituted aromatic spacer have been prepared. Their complexes with Cu2+, ... -
Recognition of Free Tryptophan in Water by Synthetic Pseudopeptides: Fluorescence and Thermodynamic Studies
WILEY-VCH Verlag GmbH & Co. KGaA (2014-06)Pseudopeptidic receptors containing an acridine unit have been prepared and their fluorescence response to a series of amino acids was measured in water. Free amino acids, not protected either at the C or the N terminus, ... -
Rim, Side Arms, and Cavity: Three Sites for the Recognition of Anions by Tetraazolium Resorcinarene Cavitands
Wiley (2016-09)Two tetrabenzoimidazolium-resorcinarene cavitands were prepared and used for the recognition of chloride, bromide, iodide, cyanide, nitrate, perchlorate, hexanoate, benzenesulfonate, and p-toluenesulfonate. Binding affinities ... -
Selective Interaction of Dopamine with the Self-Assembled Fibrillar Network of a Molecular Hydrogel Revealed by STD-NMR
Wiley (2015-09-28)A molecular hydrogel formed by a derivative of L-valine with pendant isonicotinoyl moieties interacts selectively with protonated dopamine in the presence of related compounds such as 3-methylcatechol, and protonated or ... -
Tight and Selective Caging of Chloride Ions by a Pseudopeptidic Host
WILEY-VCH Verlag GmbH & Co. KGaA (2014-06)The selective molecular recognition of chloride versus similar anions is a continuous challenge in supramolecular chemistry. We have designed and prepared a simple pseudopeptidic cage (1 a) that defines a cavity suitable ...
