Fluorescent internal charge transfer (ICT) saccharide sensor

An efficient internal charge transfer (ICT) fluorescent saccharide sensor 3 has been prepared from 2-formyl benzeneboronic acid and aniline. When saccharides interact with sensor 3 in aqueous solution at pH 8.21 the emission maxima at 404 nm shifts to 362 nm. (C) 2001 Elsevier Science Ltd. All rights reserved.
