Organic nanoparticles whose size and rigidity are finely tuned by cross-linking the end groups of dendrimers Academic Article uri icon


  • Dendrimers with molecular weights ranging from ca. 2700 to 11‚ÄČ000 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.
