terminal groups that were generated at low or high pH for the amine- or acid-
terminated dendrimers, respectively (Fig. 11.10).
In contrast, neutral hydroxy-terminated dendrimers generally exhibit hydrodyn-
amic volumes that are invariant with pH (Young et al. 1994). The structure of
carboxyl-terminated arborol dendrimers has been extensively characterized by
