Graft copolymers dendron

Regardless of the desired architecture, there are three main synthetic approaches to the preparation of diblock, dumbbell or dendronized hybrid copolymers. These involve grafting, polymerization or stepwise dendritic growth... 

Simple geometric considerations suggest that block copolymers with a (hyper-) branched hydrophobic segment of polypeptide grafts or a polypeptide dendron, like the ones described by Chen et al. [45] (PE()i33-b-PFJ233-g-PBLGlu23-269) and Frechet et al. [46] (PFOm, 227-h-[G-3]-PALLys) (Fig. 6),... 

Perhaps some of the most exciting work using one-component dendritic gelators has been performed by Stupp and co-workers. They have investigated the assembly properties of so-called dendron rod-coil molecules (Fig. 18) [59]. These dendron rod-coils are effectively tri-block copolymers, which have a flexible (coil) polymer unit attached to a well-defined linear rigid rod unit, which is, in turn, grafted to a dendritic head unit. The synthesis of...
