Colorimetric anion chemosensors based on anthraquinone: naked-eye detection of isomeric dicarboxylate and tricarboxylate anions†
Abstract
Three new colorimetric anion receptors 1–3 were synthesized and characterized. Among them, both 1 and 3 showed good sensitivity and selectivity for discrimination of maleatevs. fumarate or malatevs. tartrate by dramatic colour changes in
