Optical sensing of sulfate by polymethinium salt receptors: colorimetric sensor for heparin

Abstract

Polymethinium salts based on substituted malondialdehyde have been prepared; the salt 9 with PEG substitution showed high selectivity for sulfate anions and heparin in aqueous medium at physiological condition; intracellular imaging of heparin-rich subce
