Two metals are better than one: Main-chain heterometallic block copolymers composed of iron- and cobalt-rich blocks (see picture) were synthesized through consecutive photocontrolled ring-opening polymerization (ROP) of sila[1]ferrocenophanes and dicarba[2]cobaltocenophanes followed by oxidation of the cobaltocene-containing block. The redox properties and self-assembly of the resulting block copolymers in solution were also studied.
