Their light\u2010element composition, weak spin\u2010orbit coupling, synthetic modularity, high chemical stability, and solution\u2010processability offer attributes that are unavailable from other semiconducting materials. However, developing an understanding of how electronic structure correlates with emerging transport phenomena remains central to their application. Here, the first connections between molecular, electronic, and solid\u2010state transport in a high\u2010spin donor\u2013acceptor CP, poly(4\u2010(4\u2010(3,5\u2010didodecylbenzylidene)\u20104<jats:italic>H<\/jats:italic>\u2010cyclopenta[2,1\u2010<jats:italic>b<\/jats:italic>:3,4\u2010<jats:italic>b\u2019<\/jats:italic>]dithiophen\u20102\u2010yl)\u20106,7\u2010dimethyl\u2010[1,2,5]\u2010thiadiazolo[3,4\u2010<jats:italic>g<\/jats:italic>]quinoxaline), are provided. At low temperatures (<jats:italic>T<\/jats:italic> &lt; 180 K), a giant negative magnetoresistance (MR) is achieved in a thin\u2010film device with a value of \u221298% at 10 K, which surpasses the performance of all other organic materials. The thermal depopulation of the high\u2010spin manifold and negative MR decrease as temperature increases and at <jats:italic>T<\/jats:italic> &gt; 180 K, the MR becomes positive with a relatively large MR of 13.5% at room temperature. Variable temperature electron paramagnetic resonance spectroscopy and magnetic susceptibility measurements demonstrate that modulation of both the sign and magnitude of the MR correlates with the electronic and spin structure of the CP. These results indicate that donor\u2013acceptor CPs with open\u2010shell and high\u2010spin ground states offer new opportunities for emerging spin\u2010based applications.<\/jats:p>","DOI":"10.1002\/adma.202306389","type":"journal-article","created":{"date-parts":[[2023,11,1]],"date-time":"2023-11-01T06:08:57Z","timestamp":1698818937000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Large Room\u2010Temperature Magnetoresistance in a High\u2010Spin Donor\u2013Acceptor Conjugated Polymer"],"prefix":"10.1002","volume":"36","author":[{"given":"Hamas","family":"Tahir","sequence":"first","affiliation":[{"name":"Charles D.
