Mechanically interlocked molecules (i.e. catenanes and rotaxanes) have long been of interest to chemists because of their unique molecular structures. While small molecule systems have been explored extensively, their macromolecular counterparts have received little attention, due primarily to difficulties in synthesis. Our work focuses on employing reversible olefin metathesis reactions, mediated by functional group-tolerant ruthenium alkylidene catalysts, in the synthesis of interlocked polymers. Progress towards the synthesis of interlocked polymers using olefin metathesis will be discussed.
