Abstract
Two thiophene-based monocyclic receptors and have been studied for phosphate binding in solutions (DO and DMSO- ) by H NMR and P NMR titrations, and in the solid state by single crystal X-ray analysis. Results from H NMR titrations suggest that the ligands bind phosphate anions in a 1:2 binding mode in DMSO- , with the binding constants of 5.25 and 4.20 (in log ), respectively. The binding of phosphate to and was further supported by P NMR in DO at pH = 5.2. The crystal structure of the phosphate complex of reveals unambiguous proof for the formation of a ditopic complex multiple hydrogen bonds from NH···O and CH···O interactions.
