Scheme 1.
Synthesis of chemically-modified dendrimer materials. Epoxide-terminated alkyl chains ranging in size from C10 to C16 were reacted with the free amines on poly(amido amine) or poly(propylenimine) dendrimers of increasing generation size. In this example, PG0, or generation 0 poly(amido amine), is reacted with an alkyl epoxide.
