Novel Cleavable Block Copolymers and Functionalized Nanoporous Materials
Dr. Thayumanavan et al. have developed a facile method for synthesizing novel cleavable block copolymers useful for producing functionalized nanoporous materials. These novel cleavable block copolymers are synthesized from homopolymers generated via atom transfer radical polymerization (ATRP), and can be readily cleaved into their constituent blocks tethered to functional handles (see figure below) under very mild reaction conditions. Upon cleaving and washing with a solvent selective for a minor constituent block after microphase separation, nanoporous materials containing functional handles in the nanopores can be generated. Further nanopore functionalization can produce a variety of polymer-based composite materials.
