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.
