Unsymmetrical polymeric ladderphanes by sequential polymerization: A new approach for the template synthesis of polymers with well-defined chain length and narrow polydispersity

Nothing ROMP with that: Unsymmetrical double-stranded ladderphanes are obtained by sequential ring-opening metathesis polymerization and Glaser oxidation of norbornene appended with bisalkyne moieties. Hydrolysis of these ladderphanes gives substituted poly(m-phenylene butadiynylene)s with narrow polymer dispersity index (PDI) and well-controlled degree of polymerization.
