NOVEL DIHYDROPYRROLO[2,3-F]INDOLE-DIKETOPYRROLOPYRROLE SEMICONDUCTING MATERIALS, AND METHODS AND USES THEREOF

摘要

Described herein are heterocyclic organic compounds. More specifically, described herein are compounds based on the combination of fused pyrrole structures with diketopyrrolopyrrole structures, methods for making these compounds, and uses thereof. The compounds disclosed have improved electronic, polymerization and stability properties that allow for improved material processability and inclusion in organic semiconductor devices.
