Self-Assembly of PEG-b-PS Amphiphilic Block Copolymers Having Discrete, Hydroxyl Group End-functional PEGs as a Hydrophilic Block |
| 초록 |
Poly(ethylene glycol)s (PEGs) are non-ionic water-soluble polymers which exhibit inertness in biological environments. PEGs are widely used as hydrophilic building blocks to construct a variety of block copolymers that self-assemble into nanostructures in water. The effect of the size distribution of PEGs composing the interface of nanostructures facing biological constituents has not been studied because of their intrinsic characteristics as synthetic polymers. We report here the synthesis of monodisperse PEGs by adopting the iterative growth strategy starting from commercially available tetraEG. The adopted synthetic steps such as protection, deprotection, and coupling ensure the synthesis of PEGs having the perfectly defined molecular weight and asymmetric end functionalities. We demonstrate these monodisperse oligoEG and PEGs can be utilized to construct discrete block copolymers which self-assemble into well-defined complex nanostructures having desired surface functional groups. |
