The former one is particularly interesting, because it possesses 16 diphenylpho-

Staudinger reactions afforded the dendritic species
, which possesses two types
of end groups, that are 16 phenoxy groups on one side and 512 dimethylamino
groups on the other side (Scheme 16.7) [28].
Figure 16.2 displays the various types of dendritic structures (dendrimers, den-
drons, and special dendritic architectures) built with one phosphorus atom at each
branching point synthesized up to now, thanks to the extraordinary versatility of the
chemistry of phosphorus.
