Our results indicate that organic thin-film transistors (OTFTs) based on these new chlorinated polymers exhibit electron mobilities approaching 0.1 cm(2)V(-1)s(-1) (I-on:I-off similar to 10(6)-10(7)), with far less ambipolarity due to their lower highest occupied molecular orbital energies, and they are more stable under deleterious high-humidity conditions (RH similar to 60%) and upon submersion in water, compared with those fabricated with the parent non-chlorinated polymers. In addition, OTFTs fabricated with the new chlorinated polymers exhibit excellent operational stabilities with <3% degradations upon bias-stress test.eninfo:eu-repo/semantics/closedAccessArticle10.1557/mrc.2016.42-s2.0-84979519574
