A Colorimetric Sensing Ensemble for Heparin
Journal of the American Chemical Society, 2002A receptor possessing ammoniums and a novel amino acid with a boronic acid side chain was designed and synthesized. The receptor shows good affinity and selectivity for heparin over similar polysaccharides possessing lower anionic charge density. The affinity for heparin is similar to that for a heparin disaccharide, indicating that disaccharidic units

Squaramides for colorimetric and fluorescent anion sensing
Organic & Biomolecular Chemistry, 2023Simple squaramides bearing two fluorophores provide either colourimetric or fluorescent responses to oxoanions. Insertion of a methylene spacer between the fluorophore and squaramide leads to a ratiometirc fluorescent response to anions.
