Abstract

Poly-L-lysine (PLL) grafted ordered mesoporous material was prepared by a combination of NCA polymerization and click chemistry. Large pore SBA-15 with a mesopore diameter of∼ 12 nm was synthesized using a previously reported method. The surface of this SBA-15 material was modified with azidopropyl groups. This “clickable” SBA-15 was then reacted with an alkyne terminated poly-L-lysine synthesized by the ring-opening polymerization of ...
