There is increasing interest in electronically-functional organic materials for various applications, such as field-effect transistor, light-emitting displays, and photovoltaic cells. Perylene bisimides combine a strong absorption in the visible region with a fluorescence quantum yields near unity and high charge mobilities. Furthermore, perylene bisimides feature a relatively low reduction potential, which enables their use as an n-type semiconductor. Poly(norbornene)-based backbone has relatively little adverse effect on the charge-carrier mobilities in comparison to analogous materials based on the more polar poly(acrylate) backbone. We synthesized poly(norbornene)-based polymer with perylene in side chain as novel N-type organic semiconductor material. These polymers have been polymerized using ring-opening metathesis polymerization (ROMP), and measured electron mobilities of poly(norbornene)-based polymer and analogous poly(acrylate)-based polymer using a time of flight technique. |
