Structure arid Dynamics of Guest Molecules in Cyclophosphazene Inclusion Compounds

Abstract

2H NMR techniques are employed to study the structure and dynamics of guest molecules in Cyclophosphazene inclusion compounds. A detailed analysis of the variable temperature NMR experiments provides quantitative information about the molecular mobility of the guest components within the Cyclophosphazene channels. It is shown that the guest species are highly mobile displaying internal conformational motions and overall reorientational processes along with a considerable amount of dynamic disorder. For the overall motions a strong influence by the actual structure (or symmetry) of the organic guest molecules is registered.
