- Abstract
- Three aza-pentacyclic acenedithiophene-based conjugated polymers were synthesized using dithiophene, thieno[3,2-b]thiophene, and fluorinated dithiophene as co-units. The thermal properties, optical properties, crystal structures, and field-effect behaviors were systematically investigated. Aza-pentacyclic acenedithiophene-based conjugated polymers exhibited excellent thermal stability, narrow absorption, and highly ordered crystal structure. The organic film transistor devices prepared with the conjugated polymers as active layers were also fabricated and exhibited hole transport characteristics with the highest hole mobility of over 0.01 cm2V−1s−1. © 2023 Elsevier B.V.
