Abstract

Abstract A selective and sensitive intramolecular charge transfer (ICT) fluorescent chemosensor was designed for Cu 2+ in neutral aqueous solutions of pH 7.0. The design of this totally water-soluble fluorescent chemosensor was based on the binding motif of Cu 2+ to aminoacid, which is coupled to an ICT fluorophore bearing a 1, 3, 4-thiodiazole moiety in the electron acceptor. The formation of a 1: 1 complex of Cu 2+ to 2 was suggested to lead ...
