  • Publication number: 20220396661
    Abstract: The present invention relates to a novel polymer and an organic electronic device using same. In the polymer according to the present invention, a cyclic electron-donor, including thiophene, selenophene, or a combination thereof, is introduced into a central skeleton having an A-D-A structure including an electron-donor and electron-acceptor unit. Thus, the polymer has not only excellent chemical and thermal stability, but also good crystallinity. Moreover, intermolecular stacking is possible, and thus charge mobility can be maximized.
