A significant challenge in obtaining well defined all-conjugated block copolymers using a macroreagent approach is ensuring good functionality of the starting materials. We utilize functionalized catalysts to synthesize well functionalized polymers, as determined by 1H NMR, MALLS, and MALDI. A series of poly(9-9dioctylfluorene) and poly(3-alkylthiophene) polymers with azide and alkyne groups are synthesized and joined using copper catalyzed azide alkyne click chemistry. Crystal structure of the resulting materials is investigated using GIWAXS and microphase segregation investigated via AFM.
