Abstract

Regioregular poly(3-alkylthiophene), rr-P3AT, is a conducting polymer with numerous uses especially in the chemical and electrical sensor field. When combined with a coil type polymer, the new rod-coil block copolymer becomes attractive for nano-scale morphology control. However, one problem with rr-P3ATs is the difficulty associated with separating starting materials from the products. This can be limiting in their uses as block-copolymers and further functionalization of side chains. This difficult separation results in the need for high yielding reactions with side products that can be removed in methanol or hexanes. Based upon these requirements, Click chemistry seemed like an ideal reaction. The goal of this research was to form new block copolymers using rr-P3AT and three different coil polymers; polystyrene, polybutyl acrylate and polyethylene glycol. Additional work was done trying to synthesize rr-P3HT carbohydrate functionalized side chains.
