Abstract

A thiourea-modified fluorescein derivative was synthesized by reaction of fluorescein isothiocyanate with 2-(2-aminoethoxy) ethan-1-ol. UV/Vis absorption and fluorescence emission spectroscopy studies demonstrated that this heteroditopic receptor was able to discriminate among linear aliphatic ω-amino acids with different chain lengths.
