POLY 244 |
| Dendronized polymers are an important class of polymer architectures due to the ability to easily manipulate their size, shape, and rigidity. The most popular technique used in their synthesis is the “grafting from” approach in which dendrons are grown divergently from each repeat unit of the polymer backbone. The synthesis of a cyclic dendronized polymer was carried out utilizing a cyclic poly(hydroxystyrene) (PHS) backbone. The dendrons were then grown from the polymer backbone through a divergent technique using an extremely efficient benzylidene protected ester anhydride coupling reaction followed by deprotection of the benzylidene protecting groups. The third generation cyclic dendronized polymer was found to be water soluble due to the large amount of hydroxyl groups present on the periphery of the dendrons. Encapsulation ability of these polymers was proven by the presence of characteristic pyrene UV absorbance in aqueous solutions containing the water soluble cyclic dendronized polymers. |
