(a) Synthetic scheme of Co-containing BCPs prepared using Grubbs' third-generation catalyst. Using standard ring-opening metathesis polymerization conditions, the C16 monomer was polymerized followed by BCP chain extension using the Co-containing monomer. (b) Two representative size exclusion chromatography curves highlighting the efficiency of BCP formation. The red curve is for the C16 polymer chain, which was extended to form the diblock copolymer whose size exclusion chromatography is shown in blue.
