Replacing the 2-octyldodecyl side chain with cardanol in P(NDICL-T2) improved electron mobility due to increased chain flexibility and ordered packing. Lower glass transition temperature (tg), red-shifted UV-vis absorption, results from crystalline structure analysis, indicating tighter lamellar spacing and enhanced molecular ordering, and smoother surface morphology confirmed the enhanced intermolecular interactions and uniform film formation.<\/jats:p>","DOI":"10.3390\/mi15121475","type":"journal-article","created":{"date-parts":[[2024,12,5]],"date-time":"2024-12-05T06:24:44Z","timestamp":1733379884000},"page":"1475","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Synthesis and Electron-Transporting Properties of N-Type Polymers with Cardanol-Based Side Chains"],"prefix":"10.3390","volume":"15","author":[{"given":"Jin","family":"Cheng","sequence":"first","affiliation":[{"name":"Department of Chemical Engineering and Pharmaceutical Engineering, Changzhou Vocational Institute of Engineering, Changzhou 213164, China"},{"name":"Graduate School of Bio-Applications and Systems Engineering, Tokyo University of Agriculture and Technology, Tokyo 184-8588, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongyu","family":"Fu","sequence":"additional","affiliation":[{"name":"Graduate School of Bio-Applications and Systems Engineering, Tokyo University of Agriculture and Technology, Tokyo 184-8588, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yifan","family":"Qiao","sequence":"additional","affiliation":[{"name":"Graduate School of Bio-Applications and Systems Engineering, Tokyo University of Agriculture and Technology, Tokyo 184-8588, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuming","family":"Xue","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering and Pharmaceutical Engineering, Changzhou Vocational Institute of Engineering, Changzhou 213164, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pirada","family":"Sudprasert","sequence":"additional","affiliation":[{"name":"Faculty of Science and Technology, Rajamangala University of Technology Tawan-OK, Chonburi 20110, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9938-6748","authenticated-orcid":false,"given":"Kenji","family":"Ogino","sequence":"additional","affiliation":[{"name":"Graduate School of Bio-Applications and Systems Engineering, Tokyo University of Agriculture and Technology, Tokyo 184-8588, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"12809","DOI":"10.1039\/C9TC02632K","article-title":"Emerging research directions for n-type conjugated polymers","volume":"7","author":"Jia","year":"2019","journal-title":"J.
