ROMP with a kinky olefin : An [8]‐annulene in which one of the double bonds is kinked into a trans configuration is wound into a helical conformation, and is spring‐loaded with circa 18 kcal mol −1 strain energy. This annulene acts as an active monomer for ring‐opening polymerization (ROMP), which produces a living oligo(phenylene vinylene) (OPV) with all‐ ortho linkages. The polymer has an equal number of cis and trans double bonds.
