It has been well known that living anionic polymerization is the most established polymerization method to synthesize polymers with controlled molecular weights and narrow molecular weight distributions. From the synthetic viewpoint, successful living anionic polymerization of certain monomers allows functional block copolymers with precise macromolecular structures to be prepared by sequential addition of monomers. I previously reported the successful living anionic polymerization of triphenylamine-containing styrene through introduction of protecting group. Based on this, I am planning to present precise synthesis of block copolymers containing triphenylamine via living anionic polymerization and their applications. In particular, synthetic strategy to well-defined functional block copolymers that could be used as hole-transporting layer of organic light-emitting diodes and active layer of organic memory devices will be discussed.
