Effectual binding of gallic acid with p-sulfonatocalix[4]arene: An experimental and theoretical interpretation

The inclusion of thioflavin T (ThT) with p‐sulfonatocalix[4]arene (p‐SC4) is briefly discussed in solution as well as solid state. The restricted rotation of C−C single bond between indole and benzene ring system is the reason for emission property of ThT. The encapsulation of ThT using a flexible charged host molecule exploit the correlation between the C−C single bond rotation and emission enhancement. The binding of ThT with p‐SC4 in solution state is studied using absorption, emission, electrochemical, 1H NMR and rotating frame nuclear overhauser effect spectroscopy (ROESY) techniques. A stable water insoluble supramolecular complex is synthesized from water soluble ThT and p‐SC4. The structural features of the prepared solid complex is established from infrared (FT‐IR), powder X‐ray diffraction (XRD), Mass, 1H NMR and nuclear overhauser effect spectroscopy (NOESY) analyses.
