A novel symmetrical squaraine derivative with two phenylboronic acid functions has been synthesized. This compound detects carbohydrates in aqueous solutions with a fluorescence intensity increase. The emission maximum is at 645 nm with a gamma-band shoulder at 695 nm, making this the first example of a near IR emitting carbohydrate chemosensor. (C) 1999 Published by Elsevier Science Ltd.
