New methodologies for synthesizing conjugated polymers will be described. One example entails the ring-opening metathesis polymerization (ROMP) of dibromo Dewar benzene followed by dehalogenation of the corresponding polymer to afford trans-poly(acetylene) with high stereopurity. The mechanism of the transformation along with adaptation of the methodology to access multiblock derivatives will be described. In another example, a series of cyclobutenyl-based monomers outfitted with different functional groups was obtained through the ring-opening esterification of Dewar lactone. A novel ROMP / elimination sequence afforded a new class of poly(diene)s, which displayed physical and electronic properties in a manner that depended on the functional groups present in their constituent monomers. The Institute for Basic Science (IBS-R019) as well as the BK21 Plus Program as funded by the Ministry of Education and the National Research Foundation of Korea are acknowledged for their support.
