Boronic acid appended azo dyes–colour sensors for saccharidesElectronic supplementary information (ESI) available: absorption–pH titrations and absorption–saccharide titrations. See http://www.rsc.org/suppdata/p1/b1/b108896c/

Abstract

A number of boronic acid functionalised azo dye molecules have been prepared using a simple 3-step synthesis and their spectral properties upon complexation with monosaccharides investigated. The dyes undergo visible colour changes in aqueous solution upon addition of monosaccharide.
