NATO Advanced Research Workshop on Chemosensors of Ion and Molecule Recognition, BONAS, France, 31 August - 04 September 1996, vol.492, pp.177-188
Fluorescent chemosensors which con be excited al the red-end of the visible spectrum offer a number of advantages. Squaraines when modified appropriately, ore shown to yield such chemosensors signalling various ions in acetonitrile and water.
