Abstract:The inclusion interaction of water-soluble p-(N,N-dimethylaminomethyl)-calix[8]arene with diphenylamine-4-sulfonic acid sodium salt was investigated by fluorimetric method. When diphenylamine-4-sulfonic acid sodium salt was added into the p-(N,N-dimethylaminomethyl) -calix[8]arene solution, the emission spectrum of diphenylamioe-4-sulfonic acid sodium salt occurred to a blue shift with the enhancement of the fluorescent intensity. The results show that the formation of the inclusion complex of the p-(N,N-dimethylaminomethyl)-calix[8]arene with diphenylamine-4-sulfonic acid sodium salt. The influence factors such as the pH value of solutions, solvents on the emission and excitation spectra of the inclusion complex were studied. It indicates that diphenylamine-4-sulfonic acid sodium salt penetrated the cavity of the calix[8]arene via the static action between the sulphonyl group of diphenylamine-4-sulfonic acid sodium salt and nitrogen atom of p-(N,N-dimethylaminomethyl)-calix[8]arene and the hydrophobic interaction of the aromatic rings.
