Abstract
Molecular Modelling of ''spherical'' cyclophosphazenic dandelion dendr imers shows that the whole moieties belong to the C-3 point group, con versely 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.
