Abstract

AbstractThe hole‐transporting ability of carbazole‐containing polymers makes them attractive for applications in organic electronics. Nitroxide‐mediated radical polymerization (NMRP) offers the potential to create complex macromolecular architectures, including block copolymers, but N‐vinylcarbazole, the simplest and most widely studied carbazole monomer, is known to polymerize poorly by NMRP. Here, we investigate the NMRP of N‐ethyl‐2‐vinylcarbazole (2 VK), a monomer structurally more similar to the styrenes which are known to polymerize well by NMRP, and whose polymer offers a hole mobility an order of magnitude higher than poly(N‐vinylcarbazole). Polymerization of 2 VK from a unimolecular alkoxyamine shows a molecular weight which increases steadily with time, though termination or decomposition of the “living” radical ends is clearly evident from the progressive formation of a low‐molecular‐weight tail as conversion increases. However, a sufficient fraction of the chains remain living that P2VK‐PS diblock copolymer can be formed by chain extension of the P2VK macroinitiator with styrene.
