The inclusion interaction of p-sulfonatocalix[6]arene with trimebutine maleate was studied.
Fluorescence spectroscopy, DSC, SEM, FT-IR, NMR were applied to characterize the complex.
Trimebutine maleate is able to form inclusion complexes with p-sulfonatocalix [6]arene in a molar ratio of 1:1 at various pH values (pH = 3.00, 6.00, 8.00).
