Figure 1.

(a) Cartoon representation of a dendrimer structure highlighting its three, distinct structural motifs: The core (in light blue), the branching units forming the different G generations (in light green), and the terminal groups (in light pink). According to a consolidate dendrimer nomenclature, the core constitutes Generation 0 (G₀). Therefore, the subsequent Generations G₁, G₂, … G_n refer to the corresponding level of branching, as annotated in panel (a). (b) Molecular structure of the triethanolamine (TEA)-core poly(amidoamine) dendrimers. For clarity, in panel (b), only a dendrimer of Generation 4 (G₄) is shown.
