树枝状聚合物的分子量范围为约。使用格鲁布斯闭环复分解反应交联2700至11000个和16至64个高烯丙基醚端基。 SEC、MALDI-TOF-MS 和 AFM 的组合用于表征交联纳米颗粒。数据表明，交联后体积显着减小，刚性随之增加，这两者都可以以相当精确的程度独立控制。
Dendrimers with molecular weights ranging from ca. 2700 to 11 000 and from 16 to 64 homoallyl ether end groups were cross-linked using the Grubbs ring-closing metathesis reaction. A combination of SEC, MALDI-TOF-MS, and AFM were used to characterize the cross-linked nanoparticles. The data suggest a significant decrease in volume with cross-linking and a concomitant increase in rigidity, both of which can be controlled independently with a fair degree of precision.
