Abstract

Abstract: A binding pattern of cyclofructan 6 and p -aminobenzoic acid was disclosed using electrospray ionization mass spectrometry and nuclear magnetic resonance spectroscopy. The complex with stoichiometric composition 1:1 was formed as a result of intermolecular hydrogen bond interaction and ion dipole interaction. Spectrophotometic studies demonstrated that their binding properties could be actuated by modulating the pH from 2.0 to 10.0. This is the first demonstration of development of 'switching' binding pattern for cyclofructan 6. Graphical abstract:
