| Thiophene-based materials have been examined for a wide variety of industrial uses due to their optical and electronic properties. Recently, oligothiophenes have received particular attention as both model systems for parent polymers and as active materials in devices such as field effect transistors (FETs), light emitting diodes (LEDs), photovoltaic cells, and spintronics. Oligomers incorporating N-functionalized dithieno[3,2-b:2'3'-d]pyrrole (DTP) units have been shown to exhibit enhanced electronic and optical properties, including high solution fluorescence efficiencies (up to 53%). Due to the N-functionalized side chains, these oligomers also exhibit desirable solubility characteristics and can therefore be processed via both solution and vapor deposition techniques. To further investigate the potential of DTP-based materials, a series of DTP oligomers are being prepared as models of larger polymeric systems and as potential FET materials. These oligomers will additionally contain alkyl groups end-capping the á-positions in order to enhance stability and control solid-state organization. |
