Polymers in Functionalization Polymers are often used to control the distance between particles, to passivate them or to carry them. R. Shenhar, T. Norsten and V. Rotello Polymer‐Mediated Nanoparticle Assembly: Structural Control and Applications Adv. Mater. 2005, 17, 657 -669.
Polymers in Functionalization • Polymerization of derivatized monomers • Post-polymerization functionalization R. Shenhar, T. Norsten and V. Rotello Polymer‐Mediated Nanoparticle Assembly: Structural Control and Applications Adv. Mater. 2005, 17, 657 -669.
Polymerization of derivatized monomers Functionalize monomers that are going to form a polymer, however the functionality should be inert to polymerization process. Chain-growth polymerization • free-radical polymerization • anionic • cationic • coordination polymerization R. Shenhar, T. Norsten and V. Rotello Polymer‐Mediated Nanoparticle Assembly: Structural Control and Applications Adv. Mater. 2005, 17, 657 -669.
Post-polymerization functionalization The functional group is attached once the polymerization is completed. R. Shenhar, T. Norsten and V. Rotello Polymer‐Mediated Nanoparticle Assembly: Structural Control and Applications Adv. Mater. 2005, 17, 657 -669.
