摘要：

(Figure Presented) 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. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
