Nanostructures of n-type organic semiconductor in a p-type matrix via self-assembly of block copolymers

The block copolymerization of 4-vinyltriphenylamine and a perylene bisimide acrylate was analyzed using a nitroxide-mediated living radical polymerization. The functionalized block copolymer consists of one block with a hole transport moiety and second block with an electron transport moiety with light absorption properties. It was observed that the polymers show phase separation with increasing amounts of dye that build up in nanostructures of perylene bisimide in a PvTPA matrix over a large area. The formation of n-type organic semiconductor in a polymer matrix opens up new concept in nanoscience and molecular electronics.
