A squarylium (SQ) dye was synthesized by the reaction between squaric acid and 2,3,3-trimethylindolenine and its anion sensing properties were investigated using absorption and emission spectroscopy. This chemosensor exhibited high selectivity for CN(-) as compared with F(-), CH(3)CO(2)(-), Br(-), H(2)PO(4)(-)

The title compound, 2-(phenylethyl)ammonium hydrogensquarate hemihydrate, was synthesized and structurally and spectroscopically characterized by a single crystal X-ray diffraction and solid-state polarized IR spectroscopy of oriented colloids in a nematic host. The crystal structure consists of two crystallographically independent 2-(phenylethyl)ammonium

Contemporary medicinal chemistry faces diverse challenges from several directions, including the need for both potency and specificity of any therapeutic agent; the increasingly demanding requirements of low toxicity shown across all patients treated; and the need for novelty in intellectual

Environment-sensitive binding of anions to synthetic receptors is important for the functional mimicry of ion channels. We describe new squaramide-based chloride ion receptors whose anion binding cavity can be opened and closed by using carbonyl groups as valves. In nonpolar

A water-soluble squaric acid dialkyl diester derivative is presented, which enables one-pot, two-step amine-selective protein conjugation reactions with (functional) amines in water. This reagent not only allows all-aqueous protein modifications, but also tolerates e.g. hydroxyl groups and can also be
