We present the preparation of a series of chiral dendrons, in which chiral subunits are placed in individual generational shells at increasing distances from the focal point, by a combination of convergent and divergent dendrimer synthesis methods, Analysis of chiroptical data suggests that these dendrons do not possess conformational order in solution.
