Dendrimers with Oligospiroketal (OSK) Building Blocks: Synthesis
and Properties
Chem. Eur. J. 2015, 21, 10466-10471
DOI: 10.1002/chem.201501386 | | The development of novel dendrimers containing
oligospiroketal (OSK) rods as building blocks is described.
The linkage between the core unit (CU), branching units
(BU), and OSK rods relies on the CuAAC reaction between
terminal alkynes and azides. Two different strategies of dendrimer
synthesis were investigated and it was found that the
convergent approach is clearly superior to the divergent
one. SAXS measurements and MD simulations indicate that
the obtained dendrimer features a globular structure with
very low density. Obviously, the OSK rods stabilize a rather
loose mass-fractal structure. | | Zurück zur Übersicht » |
