Since a suitable monomer has not yet been demonstrated, we decided to pursue a route for ROMP monomer preparation that would allow rapid variation of the pendant group. Nhydroxysuccinimide (NHS) esters are a well known class of "active ester" compounds, where the NHS group can be readily replaced by a variety of nucleophiles. Amines are the most commonly used nucleophile in this type of reaction, with the product being an amide and free NHS. As a strategy for monomer synthesis, this technique could be used for quick preparation of various ROMP monomers bearing electropolymerizable pendant groups. However, a post-polymerization functionalization strategy is possible as well and might be the most efficient approach. Living radical polymerization has been used in the literature to produce polymer brushes with an NHS ester sidechain, which can then be quantitatively reacted with an amine-containing species. Because of this reported versatility, we felt that a similar postfunctionalization strategy could be a good route for preparing molecular-wire type architectures through a surface-bound ROMP graft copolymer. Using a monosubstituted NHS active ester brush, it should be relatively easy to determine end-functionalization conditions for the system, since monosubstituted Nb monomers generally have a living regime in their ROMP polymerization. In this strategy, the end-functionalization can be performed independently of the attachment and polymerization of the conducting polymer co-monomer, allowing a variety of conductive graft copolymers to be investigated without the need to rediscover the conditions for end-functionalization (the most difficult part of the experiment) in each instance.
