Poly(1,6‐hexane‐9,9,9′,9′,9″,9″‐hexahexyl‐7,2′;7′,2″‐terfluorene‐2,7″‐dicarboxylate) (PTFHHC6) has been synthesized and characterized. This polymer exhibits strong emission in the blue range, both in solution (quantum yield of 76%) and in the solid state. Moreover, PTFHHC6 presents some advantages over other polyfluorene derivatives since its solid‐state fluorescence spectrum does not show any excimer formation and does not vary upon thermal treatment. Electrochemical measurements have revealed a reversible p‐n dopable polymer. This aromatic polyester shows promising optical and electrical properties for the development of blue light‐emitting diodes.
