Determination of SDS using fluorescent γ-cyclodextrin based on TICT in aqueous solution.
Fluorescent γ-cyclodextrin derivatives, modified using N-phenyl-x-anthracenecarboxamido (ACs; x = 9, 1), were synthesized and investigated using fluorescence and UV-vis spectroscopy.  Fluorescence enhancements of ACs were observed up to 12-fold by the addition of sodium dodecyl sulfate (SDS) below the critical micellar concentration (CMC).  In the presence of a nonionic surfactant, such as Triton X-100, fluorescence spectra were scarcely changed.  The fluorescence selectivity between SDS and Triton X-100 was clarified from the different spectral behaviors by circular dichroism and (1)H NMR spectroscopies.
