      Solution-processable conjugated oligomers incorporating red-light   absorbing azadipyrromethenes (aza-DIPY) within the main chain   were synthesized via palladium-catalyzed Sonogashira coupling   reactions. Thin films of these compounds absorbed light up   to1000   nm and displayed reversible reductions as ascertained by cyclic   voltammetry experiments. Reactions with trifluoroboron etherate   yielded materials displaying a unique combination of good   solubility in organic solvents, low optical band gaps   (1.3   eV), and high electron affinity (4.5   eV).
