Three boronic acid based saccharide sensors with an aniline fluorophore have been prepared. One of the systems (1a) contains an intramolecular boron-nitrogen (B-N) bond and displays fluorescence due to both LE and TICT states. The other two systems (1b and c) have no B-N bond and only Show fluorescence due to the LE state. (C) 2004 Elsevier Ltd. All rights reserved.
