Abstract

Three new alternating conjugated polymers consisting of pyrene and 3-dodecylthiophene (PPyMT), 4,4′-didodecyl-2,2′-bithiophene (PPyBT), or 9,9-didodecylfluorene (PPyFlu) moieties have been prepared using Suzuki coupling reaction or Sugimoto approaches. The polymers were readily soluble in common organic solvents and exhibited good thermal stability in nitrogen and air atmospheres. The structures and optical properties of the polymers were characterized by NMR, FTIR, XRD, UV–vis, and fluorescence spectroscopy. PPyMT and PPYBT showed blue-light emission in solution, whereas PPyFlu performed blue-light emitting in film state. The polymers exhibited an intermolecular aggregation and structural ordering due to pyrene–pyrene π–π stacking interaction. © 2010 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2010
