Concerning the localization of end groups in dendrimers

A wide range of N-t-BOC-protected glycine functionalized dendrimers were synthesized by reacting the N-hydroxy succinimidyl ester of N-t-BOC glycine with poly(propylene imine) amines and characterized via nuclear magnetic resonance and infrared spectroscopy. The X-ray structure of the dendrimers exhibited multiple interactions between various end groups of the dendrimer. The findings provided strong evidence that the localization of end groups as well as the density profiles in dendrimers are a function of the structure of the dendrimer.
