Poly(1,6-hexane-9,9,9',9',9",9"-hexahexyl-7,2';7'2"-terfluorene-2,7"-dicarboxylate) (PTFHH-C6) 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.
