Postsynthetic modification at the focal point of a hyperbranched polymer.
Functionalization at the focal point of hyperbranched polyester was achieved using a series of amines and a postsynthetic reaction utilizing an activated p-nitrophenyl ester unit. An element of dense packing was also detected, as evident from differences in levels of incorporation between linear and bulky reagents.
