Pyrrolo - pyrrole-dione - thiophene quinone compounds, methods of preparation and use thereof

摘要

Pyrrolo represented by the formula I - pyrrole-dione - thiophene quinone compounds, their use as a preparation and an organic semiconductor material is disclosed. Preparation method for the compounds of formula I, the catalyst Pd (PPh ₃₎ NaH in the presence of _{4, α-} bromo-substituted pyrrolo represented by the formula II - pyrrole-dione - a step of reacting a thiophene oligomer and malononitrile sodium salt , followed by carrying out the oxidation reaction by the addition of saturated bromine water to the reaction system, and a step for obtaining a compound of formula I. The compounds of formula I, a field-effect performance is satisfactory, the electron mobility is higher than 0.1cm ² V ^-1 s ^-1, the on / off current ratio is up to 10 ⁵ are stable in air.
