ABSTRACT: The
aqueous solution of p-Sulfonatocalix[4]arene-fluorescein complex has been
studied based on fluorescence and 1H NMR spectroscopic results. It has been
found that the fluorescence intensity quenches regularly upon addition of
p-SCX4. The proposed interaction mechanism between p-SCX4 and FL indicates that
FL partially goes into the cavity of p-SCX4 with the help of strong
electrostatic and π-π* interaction. The quenching constants and stability constants
are determined by p-SCX4-FL systems. The proposed inclusion complex is
discussed on 1H NMR results. Results are consistent with experimental data
obtained from NMR spectroscopy.
