  Low-Bandgap Benzodifuranone-Based Polymers

  摘要：

  pi-Conjugated monomers and polymers containing benzodifuranone units in the main chain were prepared. Polymers were obtained using palladium-catalyzed Suzuki and Stifle polycondensation reactions of dibromo-substituted benzodifuranone derivatives with either dihexylfluorene diboronester or bis(trimethylstannyl)thiophene. The optical and electronic properties were investigated using UV/vis absorption spectroscopy and cyclic voltammetry. It was found that the polymers show very broad absorption bands with a high extinction coefficient up to 32500 L mol(-1) cm(-1). The polymers also show reversible redox behavior, giving small HOMO-LUMO gaps up to 1.30 eV with strong donor-acceptor character.

  The present invention relates to polymers comprising one or more (repeating) unit(s) of the formula (I): wherein Y is a group of formula (AA), or (BB) and their use as organic semiconductor in organic devices, especially in organic photovoltaics (solar cells) and photodiodes, or in a device containing a diode and/or an organic field effect transistor. The polymers according to the invention have excellent solubility in organic solvents and excellent film-forming properties. In addition, high efficiency of energy conversion, excellent field-effect mobility, good on/off current ratios and/or excellent stability can be observed, when the polymers according to the invention are used in organic field effect transistors, organic photovoltaics (solar cells) and photodiodes.
