卡通结构图表示的树枝状聚合物
图一:一个第三代树枝状聚合物的具体例子。树枝状聚合物表面的胺基可以被修饰成不同的官能团或者被保护基团保护。下角标n表示的重复单元的数目。
图二:原子力显微镜扫描的高度图。图像显示的是一代到四代的树枝状聚合物的混合物(PG1 - PG4),图像很清楚的表现了不同代数的树枝状聚合物的差异,例如:高度、直径、刚性。
图三:两种主要合成路线:大单体路线(左)和attach-to路线(右)。

树枝状聚合物,又称树枝化聚合物,是每个重复单元上带有树枝化基元(dendron)的线状聚合物。

Dendronized polymer 树枝状聚合物

(重定向自Dendritic polymer)
chemical structure of a third generation dendronized polymer
Figure 4. The two main synthetic approaches: The macromonomer route (left) and the attach-to route (right).

Dendronized polymers. (or dendronised polymers) are linear polymers to every repeat unit of which dendrons are attached. Dendrons are regularly branched, tree-like fragments and for larger ones the polymer backbone is wrapped to give sausage-like, cylindrical molecular objects. Figure 1 shows a cartoon representation with the backbone in red and the dendrons like cake slices in green. It also provides a concrete chemical structure showing a polymethylmethacrylate (PMMA) backbone, the methyl group of which is replaced by a dendron of the third generation (three consecutive branching points).
