Why “Spherical” Cyclophosphazenic Dandelion Dendrimers Have a Dipole Moment?

Abstract

Molecular Modelling of “spherical” cyclophosphazenic dandelion dendrimers shows that the whole moieties belong to the C₃ point group, conversely to the starting material, N₃P₃Cl₆, which is of D_3h symmetry. Moreover, these spherical dendrimers actually have significant dipole moments due to a non-centrosymmetrical distribution of the lone pairs of the nitrogen atoms of their amino groups and functions.
