The complexation of sulfanilamide with different crown ethers has been studied by 1H NMR, IR and UV?visible spectra in solution state. The interactions of crown ethers with sulfanilamide have been supported by density, viscosity, refractive index indicating higher degree of complexation in case of dicyclohexano-18-crown-6. The complexation stoichiometry was determined by Job plots and the 1:1 stoichiometry is found for all the complexes; the complex formation is confirmed by spectral shifts. The Benesi-Hildebrand method is used to calculate the binding constant of the complexes of sulfanilamide with crown ethers. The Gibbs free energy change of the inclusion complex process is calculated and the process is found to be spontaneous. Hydrogen bonding was observed to be the most important interaction for the complexation and pi?pi interactions also have minor contribution towards complexation of dibenzo-18-crown-6. Various factors that influence the stability of the complexes formed have been discussed for thermodynamic consideration.
