Abstract
A thermodynamic and spectroscopic investigation has been carried out o n the protonation and copper(II) complexation of the 6-diethylenetriam ine derivative of beta-cyclodextrins. By C-13 NMR titration, the order of protonation of the three nitrogen atoms has been ascertained. The unusual entropy changes accompanying the different steps of protonatio n, as well as the copper(II) complexation, are discussed.
