Ferrocenophanes, ring-opening metathesis polymerization

Vinylene-bridged [2]ferrocenophanes [35] or diene-bridged [4]ferrocenophanes [36] have been utilized as monomers in a ring-opening metathesis polymerization by the use of molybdenum catalysts (Fig. 8.10). 

Ring-opening metathesis polymerization (ROMP) of ferrocenophanes containing bridging olefinic groups (45, 46 48) has been examined in order to synthesize conjugated ferrocene-based polymers (93-95). The poljuners synthesized... 

The ring-opening metathesis polymerization of ferrocenophanes containing bridging vinyl groups has also been reported/ " The incorporation of alkyl groups pendent to their backbones increased the solubility of these polymers (18). An enhancement of solubility could also be achieved by copolymerization reactions. Some of these polymers exhibited electrical conductivity.
