And higher\u2010acenes (&gt;7 rings) with big beautiful structures are more likely to be continuously pursued. However, the instability, poor solubility, and challenging synthesis of higher\u2010acenes significantly hinder their fundamental investigation. Of greater concern is that no stable n\u2010type higher\u2010acene analogues have been obtained to date. Here, using oxazine and benzene units as the building blocks, a novel series of higher\u2010acene analogues (9 rings) named pentaphenotetraoxazines (\n                    <jats:bold>PPTOs)<\/jats:bold>\n                    , is synthesized by chemical solution method. These compounds exhibit high solubility in common organic solvents, high stability under ambient conditions, deep lowest unoccupied molecular orbital levels below \u22124.1\u00a0eV, strong NIR absorbance, and narrow optical bandgap (&lt;1.4\u00a0eV). In solution\u2010processed organic field\u2010effect transistors (OFETs), the devices demonstrate electron mobilities exceeding 0.1\u00a0cm\n                    <jats:sup>2<\/jats:sup>\n                    \u00a0V\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u00a0s\n                    <jats:sup>\u22121<\/jats:sup>\n                    , which are two and three orders of magnitude higher than those of prior reported higher\u2010acene analogues and the homologous 5\u2010ring derivative\u2014triphenodioxazine (\n                    <jats:bold>TPDO<\/jats:bold>\n                    ), respectively. Moreover, these n\u2010type OFETs demonstrate excellent stability under ambient conditions without encapsulation. These results highlight the high stability and outstanding n\u2010type semiconductor performance of oxazine\u2010fused higher\u2010acene analogues and demonstrate the potential of this strategy to develop even larger acene systems.\n                  <\/jats:p>","DOI":"10.1002\/anie.8366566","type":"journal-article","created":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T12:02:47Z","timestamp":1785326567000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["n\u2010Type Oxazine\u2010Fused Higher\u2010Acene Analogues With High Stability and High Charge Mobility"],"prefix":"10.1002","volume":"65","author":[{"given":"Fang","family":"Sun","sequence":"first","affiliation":[{"name":"State Key Laboratory of Fine Chemicals Frontiers Science Center for Smart Materials Oriented Chemical Engineering School of Chemical Engineering Dalian University of Technology  Dalian Liaoning Province P.R.
