The inclusion of TIT imparted degradability to the random copolymers under acidic conditions, offering a sustainable solution for electronic waste management. Structural analysis revealed that TIT favored edge\u2010on molecular orientation, while TVT promoted face\u2010on and end\u2010to\u2010end orientations. The synergistic combination of TIT and TVT in copolymerization resulted in balanced structural and functional properties with partial degradability conferred using the TIT units. The random copolymer <jats:bold>P3<\/jats:bold>, with an optimal equimolar TIT\/TVT ratio, demonstrates superior electrical and mechanical performance. <jats:bold>P3<\/jats:bold> exhibits an initial charge mobility of 0.10\u00a0cm<jats:sup>2<\/jats:sup>\u00a0V\u207b\u00b9\u00a0s\u207b\u00b9 and maintained mobility of 0.0017\u00a0cm<jats:sup>2<\/jats:sup>\u00a0V\u207b\u00b9\u00a0s\u207b\u00b9 under 20% strain, significantly outperforming <jats:bold>P1<\/jats:bold> in mobility at almost strain levels. <jats:bold>P3<\/jats:bold> also achieved a mobility retention of 31.3% under 20% strain, compared to 12.2% for <jats:bold>P5<\/jats:bold>. This study demonstrates that the copolymerization of TIT and TVT enables the fine\u2010tuning of solid\u2010state packing modes and molecular orientations, thereby improving both the stretchability and environmental sustainability of the materials.<\/jats:p>","DOI":"10.1002\/marc.202401057","type":"journal-article","created":{"date-parts":[[2025,2,3]],"date-time":"2025-02-03T07:43:57Z","timestamp":1738568637000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Partially Degradable N\u2010Type Conjugated Random Copolymers for Intrinsically Stretchable Organic Field\u2010Effect Transistors"],"prefix":"10.1002","volume":"46","author":[{"given":"Chia\u2010Hsueh","family":"Chung","sequence":"first","affiliation":[{"name":"Department of Chemical Engineering National Cheng Kung University  Tainan City 70101 Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu\u2010Chun","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering National Cheng Kung University  Tainan City 70101 Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shang\u2010Wen","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering National Cheng Kung University  Tainan City 70101 Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun\u2010Jen","family":"Su","sequence":"additional","affiliation":[{"name":"National Synchrotron Radiation Research Center  Hsinchu 300092 Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"U\u2010Ser","family":"Jeng","sequence":"additional","affiliation":[{"name":"National Synchrotron Radiation Research Center  Hsinchu 300092 Taiwan"},{"name":"Department of Chemical Engineering &amp; College of Semiconductor Research National Tsing Hua University  Hsinchu 300044 Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jung\u2010Yao","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Photonics National Cheng Kung University  Tainan City 70101 Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2914-6762","authenticated-orcid":false,"given":"Yan\u2010Cheng","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering National Cheng Kung University  Tainan City 70101 Taiwan"},{"name":"Advanced Research Center for Green Materials Science and Technology National Taiwan University  Taipei 10617 Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,2,2]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.1002\/adfm.201904545"},{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrev.2c00696"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1021\/jacs.2c00072"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.202209896"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.202201623"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-024-46493-4"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-022-04400-1"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41563-023-01529-w"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cej.2023.145121"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/smll.202401966"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.progpolymsci.2019.101181"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemmater.0c03019"},{"key":"e_1_2_8_13_1","first-page":"138","volume":"4","author":"Ding Z.","year":"2024","journal-title":"Interd.
