Novel linear and tribranched polymers with redox-active end groups via W(CO)6-initiated metathesis polymerization.
[reaction: see text] Synthesis, characterization, and electrochemistry of linear and tribranched polyphenylacetylenes having redox-active ferrocene and/or (arene)chromiumtricarbonyl as end groups are reported in this study. The methodology adopts polymerization of phenylacetylene by a metathesis pathway, initiated by W(CO)(6) when photolyzed. A distance-dependent electronic communication between the metal centers is demonstrated in these polymers by means of cyclic voltammetry.
