Figure 5From: Dendrimers: synthesis, applications, and propertiesApproaches for the synthesis if dendrimers. (A) Divergent approach: synthesis of radially symmetric polyamidoamine (PAMAM)dendrimers using ammonia as the trivalent core; the generations are added at each synthetic cycle (two steps), leading to an exponential increase in the number of surface functional groups [37]. (B) Convergent approach: synthesis of dendrons or wedges or branches that will become the periphery of the dendrimer when coupled to a multivalent core in the last step of the synthesis [13].Back to article page
