|Title:||Physico-chemical Characterization Of The Inclusion Complex Between A 2-propen-1-amine Derivative And β-cyclodextrin|
|Abstract:||Inclusion complexes and physical mixtures were prepared with isomeric mixture of E/Z (50:50) of 3-(4′-bromo-[1,1′-biphenyl]-4-yl)-3-(4- bromophenyl)-N,N-dimethyl-2-propen-1-amine (BBAP) and β-cyclodextrin (β-CD) in different proportions. In this study, theoretical calculations using Molecular Mechanics MM+ force field were applied to predict the structures of the inclusion complexes formed by interaction of BBAP and b-cyclodextrin. Circular dichroism, differential thermal analysis (DTA), X-ray diffraction and 13C CP/MAS NMR methods were used to characterize the inclusion complexes and provide information about the stoichiometry of the inclusion complexes. The combined spectroscopy techniques indicate the formation of a complex of BBAP/β-CD in the molar proportion of 1:1 and 1:2 by co-evaporation and no complexation was detected in the physical mixture of the compounds. © 2006 Sociedad Chilena de Química β-.|
