Abstract:
We report the syntheses and characterization of two bent dialkoxy‐substituted naphthodithiophene (bNDT) isomers as well as of the corresponding bNDT‐based small molecule and polymer semiconductors for organic field‐effect transistors and organic photovoltaics. The bNDT‐based building blocks exhibit improved oxidation potential and photo‐ and air stability versus the benzodithiophene and linear naphthodithiophene counterparts. Incorporation of the dialkoxy substituents enables film fabrication from solution and control of the molecular solid‐state packing. Among these semiconductors, the polymer P1 exhibits good hole field‐effect mobility of about 0.4 cm 2 Vs −1 with I on / I off 〉 10 4 for low‐temperature annealing. These results indicate that bNDT is a promising building block for optoelectronic semiconducting materials.
