제목 Synthesis of A2B Miktoarm Star Copolymers Composed of Regioregular Poly(3-hexylthiophene) and Poly(2-vinylpyridine) containing rigid core
초록 The π-π interaction between P3HT arms in Miktoarm star copolymer composed of P3HT and P2VP ((P3HT)2P2VP) was strong enough to arrange two P3HT backbone chains in (P3HT)2P2VP to stack one by one along the nanofibril axis on thin film. This is because of very small π-π stacking distance between P3HT backbones compared with the size of the core. Here, we report a facile synthesis of (P3HT)2P2VP containing rigid core. First, we synthesized coupled P3HT having aldehyde group at the center using Suzuki reaction between 4-(bis(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)amino)benzaldehyde and H/Br terminated P3HT. The aldehyde at center in coupled P3HT was reacted with P2VP living anion using Anionic coupling. Then, column chromatography was conducted to get pure (P3HT)2P2VP. The optical property and self-assembly of (P3HT)2P2VP was investigated.
