Controlled synthesis and hexagonal assemblies of well-defined polyoxazoline-<i>block</i>-polyisocyanides copolymers.

Abstract

Well-defined poly(2-ethyl-2-oxazoline)- block -poly(phenyl isocyanide) copolymers with controlled molecular weights and narrow dispersities were synthesized by combining living cationic ring-opening polymerization (CROP) and Pd(II)-initiated isocyanide polymerization. The resulting copolymers self-assembled into uniform hexagonal assemblies whose dimensions could be tuned by varying the chain length of the poly(phenyl isocyanide) block.
