A novel squaraine with a lariat-crown ether cation-receptor unit was synthesized and shown to selectively respond to Na+ ions in polar protic solvents. The selectivity of the novel ligand, together with the impressive spectroscopic properties of squaraines yields a promising chemosensor, (C) 1998 Elsevier Science Ltd. All rights reserved.
