Unlike the situation with nonconductive polymers where variety of polymer architectures (block copolymers, polymer brushes, start, etc.) are readily available, a synthetic toolbox is much less developed in the case of conjugated (conductive) polymers. Recently, we developed surface/site-initiated Ni- and Pd-mediated catalyst transfer chain-growth polycondensations. To date, methods to grow conductive polymer brushes, hairy particles and stars of regioregular poly(3-alkylthiophenes), polyfluorenes and other conjugated polymers were developed. In this talk I would like to review our recent results in this field, including application of the obtained structures in photovoltaics and discuss an intriguing ring-walking polycondensation mechanism, responsible for the selective formation of such structures.
