TY - JOUR A1 - Wessig, P. A1 - Budach, D. A1 - Thünemann, Andreas T1 - Dendrimers with oligospiroketal (OSK) building blocks: synthesis and properties JF - Chemistry - A European journal N2 - 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.
