โœฆ Synopsis

A novel squaraine with a lariat-crown ether cation-receptor unit was synthesized and shown to selectively respond to Na รท ions in polar protic solvents. The selectivity of the novel ligand, together with the impressive spectroscopic properties of squaraines yields a promising chemosensor.

We have synthesized and spectrally characterized a squaraine-based fluorescent chemosensor for pH. This ehemosensor unlike many others, works in 100 % aqueous solutions, signalling the pH change from 10 to 7 by a 14-fold increase in the emission intensity at 651 nm, when excited at the isosbestie po
