Architecture represents a promising yet underutilized control element in polymer design due to the challenging synthesis of compositionally varied branched copolymers. We report the one-pot synthesis of miktoarm branched polymers by ring-opening metathesis polymn. In this work, we graft to and from telechelic poly(3-hexylthiophene), which is end-capped by oxime click chem., using various norbornene monomers. The self-assembly of the resulting miktoarm H-shaped conjugated polymers is studied in soln. and in the solid state. A dual stimuli-responsive miktoarm polymer is prepd. that displays pH-switchable lower crit. soln. temp. and fluorescence.
