Although high-spin ground states have been observed in some quinoidal type small molecules or doped organic semiconductors, semiconducting polymers with high-spin at their neutral ground state are rarely reported. Here we report three high-mobility semiconducting polymers with different spin ground states. We show that polymer building blocks with small singlet-triplet energy gap (ΔES-T) could enable small ΔES-T gap and increase the diradical character in copolymers. We demonstrate that the electronic structure, spin density, and solid-state interchain interactions in the high-spin polymers are crucial for their ground states. Polymers with a triplet ground state (S = 1) could exhibit doublet (S = 1/2) behavior due to different spin distributions and solid-state interchain spin-spin interactions. Besides, these polymers showed outstanding charge transport properties with high hole/electron mobilities and can be both n- and p-doped with superior conductivities. Our results demonstrate a rational approach to high-mobility semiconducting polymers with different spin ground states.</dc:description> <dc:identifier>https://archive.materialscloud.org/record/2022.46</dc:identifier> <dc:identifier>doi:10.24435/materialscloud:58-27</dc:identifier> <dc:identifier>mcid:2022.46</dc:identifier> <dc:identifier>oai:materialscloud.org:1300</dc:identifier> <dc:language>en</dc:language> <dc:publisher>Materials Cloud</dc:publisher> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode</dc:rights> <dc:subject>Organic semiconductor</dc:subject> <dc:subject>High-spin materials</dc:subject> <dc:subject>High-mobility polymers</dc:subject> <dc:title>High-mobility semiconducting polymers with different spin ground states</dc:title> <dc:type>Dataset</dc:type> </oai_dc:dc>
